[0041] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0042] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0043] The traditional server chassis includes a box body, an upper cover and a connecting rod sliding structure. In order to ensure the stability of the connection between the box body and the upper cover, grooves are provided on both sides of the box body along the width direction, and the grooves are inclined in the length direction of the box body. In view of the large volume of the box body, the connecting rod sliding structure installed on the upper cover needs to drive the upper cover to slide a certain distance in the groove, so that the staff can directly lift and remove the upper cover from the groove during installation and maintenance, thereby simplifying the operation process.

[0044] The connecting rod sliding structure includes a handle, a connecting rod, a slider and a limiting column. The handle is rotatably connected to the connecting rod and the slider respectively; the connecting rod has a through hole, one end of the limiting column is connected to the box body, and the other end passes through the through hole of the connecting rod. The connecting rod is slidably connected to the upper cover, and the slider abuts against the upper cover. The rotation of the handle can enable the slider to push the upper cover to slide relative to the box body. When the handle stops rotating, the limiting column extends out of the connecting rod to form a self-locking state, which effectively prevents the box body and the upper cover from relative displacement under the action of external force, thereby ensuring the stability of the connection between the two.

[0045] However, the inventors noticed that when the upper cover is deformed due to external forces or other factors, the other end of the limit column may not be able to extend into the through hole of the connecting rod, thereby affecting its self-locking function and the stability of the connection between the upper cover and the box body.

[0046] In response to the above problems, the present application sets a base 3 on the box body, and rotatably connects the handle assembly 2 on the bracket 1 connected to the upper cover. The relative positions of the base 3 and the bracket 1 are fixed through the mutual cooperation of the base 3 and the handle assembly 2 to ensure the stability of the connection between the box body and the upper cover.

[0047] Example 1

[0048] like Figures 1 to 6 As shown, Embodiment 1 of the present application provides a fixing structure, including:

[0049] Bracket 1, used for connecting with the upper cover;

[0050] A handle assembly 2 is rotatably connected to the bracket 1;

[0051] The base 3 is used to connect with the box body; the base 3 is arranged opposite to the bracket 1, and the handle assembly 2 is connected to the base 3 and rotates relative to the bracket 1 to a first state so that the relative position of the bracket 1 and the base 3 can be fixed.

[0052] Specifically, the thickness direction of the server chassis is set as the first direction A, the width direction of the server chassis is set as the second direction B, and the length direction of the server chassis is set as the third direction C.

[0053] The bracket 1 is used as a connecting component to be firmly connected to the upper cover of the server chassis. The bracket 1 is opposite to the upper cover along the first direction A, and the bracket 1 can be connected to the upper cover by bolts, clamping, etc. The shape and structure of the bracket 1 can be designed according to actual needs. For example, the bracket 1 can be in the shape of a box as a whole, the bottom of the bracket 1 is close to the box body, and the side wall of the bracket 1 away from the bottom can extend to the outside of the bracket 1 to form a mounting portion 12. The mounting portion 12 can be provided with a first mounting hole 121 that passes through the first direction A, and is connected to the upper cover through the first mounting hole 121. The upper cover is provided with an interface that matches the shape and size of the bracket 1 to ensure that the bracket 1 can be installed on the upper cover.

[0054] The handle assembly 2 has a locking function to ensure the stability of the connection between the bracket 1 and the base 3 in the closed state. The handle assembly 2 can be connected to the side wall of the bracket 1 by rotation around the second direction B. The handle assembly 2 has a locking device, and the locking device can be a hook-type locking device or a rotating locking device. When the user rotates the handle assembly 2 from the first state (locked state) to the second state (unlocked state), the locking device disengages from the bracket 1 and / or the base 3, so that the bracket 1 and the base 3 can move relative to each other along the first direction A to achieve equipment maintenance and installation operations; after the operation is completed, the user rotates the handle assembly 2 from the second state to the first state, at which time the locking device is locked with the bracket 1 and / or the base 3, so that the bracket 1 and the base 3 are locked, ensuring the stability of the connection between the upper cover and the box body, effectively resisting external interference, and ensuring the safe operation of the internal equipment of the server chassis.

[0055] The base 3 is used to reliably connect with the box body of the server chassis. The base 3 is opposite to the box body along the first direction A. The base 3 can be provided with a second mounting hole 32 penetrating along the first direction A, such as a threaded hole or a slot, so as to be connected with the box body by bolts or clamping. The base 3 and the bracket 1 can be arranged relative to each other along the first direction A, and the base 3 and the bracket 1 can move relative to each other along the third direction C to realize the opening and closing of the box body and the upper cover.

[0056] The fixed structure provided in Example 1 of the present application adopts a bracket 1 connected to the upper cover, and a handle assembly 2 rotatably connected to the bracket 1. Through the rotation of the handle assembly 2, when the handle assembly 2 rotates to the first state, the handle assembly 2 is in a locked state, the relative position of the bracket 1 and the base 3 is fixed, and the bracket 1 and the base 3 will not move relative to each other under the action of external force; when the handle assembly 2 rotates to the second state, the handle assembly 2 is in an unlocked state, and the bracket 1 can move relative to the base 3 to realize the opening or closing of the upper cover. The fixed structure of the present application abandons the limit column structure in the traditional connecting rod sliding structure that is easily affected by the deformation of the upper cover, and adopts a more reliable handle assembly 2 as a locking mechanism, which reduces the risk of unstable connection between the box body and the upper cover due to deformation of the upper cover, and ensures the stability of the connection between the upper cover and the box body.

[0057] The fixing structure of the present application can be used in combination with a conventional connecting rod sliding structure to enable the upper cover to slide a certain distance relative to the box body; or, in order to simplify the overall structure of the server chassis, such as Figures 1 to 4 , Figure 7 and Figure 8 As shown, in some embodiments, the handle assembly 2 includes:

[0058] A handle 21, a first side of the handle 21 being rotatably connected to the bracket 1 via a rotating member;

[0059] The first locking portion 22 is an arc segment on the first side of the handle 21 . The base 3 is provided with a first connecting portion 31 adapted to the arc segment. The first connecting portion 31 is used for plugging the arc segment with the base 3 .

[0060] Specifically, the first side of the handle 21 can be connected to the bracket 1 by rotation along the second direction B through a rotating member. The handle 21 can be in a shape that is easy to operate, such as a bar or a handle. The rotating member can be a rotating shaft or a hinge, etc. When the rotating member is a rotating shaft, the rotating member can be fixedly connected to the first side of the handle 21 and embedded in the shaft hole of the bracket 1, so as to realize the rotation connection between the rotating member and the bracket 1 around the second direction B.

[0061] The first side of the handle 21 is bent toward the base 3 to form an arc segment. The first connecting portion 31 can be a groove, a bayonet or a hole structure adapted to the shape of the arc segment. The arc segment is plugged into the base 3 through the first connecting portion 31.

[0062] When the handle 21 rotates in the second direction B, the arc segment can apply pressure to the base 3 through the first connecting portion 31. Since the weight of the box connected to the base 3 is much greater than the weight of the upper cover connected to the bracket 1, the base 3 itself will not move due to the pressure of the arc segment. At this time, the bracket 1 is subjected to the reaction force of the pressure applied by the arc segment, causing the bracket 1 to slide along the third direction C relative to the base 3, so that the upper cover is detached from the groove of the box, which is more convenient for disassembly of the upper cover.

[0063] like Figures 1 to 4 , Figure 7 and Figure 8 As shown, in some embodiments, the handle assembly 2 includes:

[0064] The second locking portion 23 is arranged on the second side of the handle 21; the bracket 1 and / or the base 3 is provided with a second connecting portion 11 adapted to the second locking portion 23, and the second connecting portion 11 is used to connect the second locking portion with the bracket 1 and / or the base 3, so that the handle assembly 2 can be rotated to the first state to fix the relative position of the bracket 1 and the base 3.

[0065] Specifically, the second locking portion 23 cooperates with the second connecting portion 11 to limit the rotation of the handle 21 around the second direction B, ensuring that the handle 21 remains stable in the locked state and will not be accidentally unlocked due to external force. The shape and size of the second connecting portion 11 are precisely matched with the second locking portion 23 to ensure that the two can be firmly connected. The position and number of the second connecting portion 11 are coordinated with the second locking portion 23 to ensure that when the handle 21 rotates to the first state, the second locking portion 23 can accurately and firmly cooperate with the second connecting portion 11 to ensure the locking relationship between the handle assembly 2 and the bracket 1 and the base 3.

[0066] like Figures 1 to 4 , Figure 7 and Figure 8 As shown, in some embodiments, the second locking portion 23 has a first clamping structure 231, which is rotatably connected relative to the handle 21, and the first clamping structure 231 is used to connect to the second connecting portion 11. The first clamping structure 231 rotates to the first position to fix the relative position of the bracket 1 and the base 3.

[0067] Specifically, the first clamping structure 231 may include a connector 2311, a screw 2312, and a locking piece 2313. A through hole may be provided on the second side of the handle 21 along the first direction A, and one end of the connector 2311 may be rotatably connected to the handle 21 through the through hole; the screw 2312 may be threadedly connected to the other end of the connector 2311, and the screw 2312 and the connector 2311 may jointly clamp the locking piece 2313, and the connector 2311 may drive the locking piece 2313 to rotate during the rotation process. The connector 2311 may be a cross screw 2312 to facilitate the user's rotation operation.

[0068] The base 3 or the bracket 1 may be provided with an avoidance hole or avoidance groove along the first direction A as the second connection portion 11. In order to enhance the effect of fixing the relative position of the bracket 1 and the base 3, it is preferred to provide an avoidance hole or avoidance groove on the base 3 along the first direction A. The shape and size of the avoidance hole may be designed according to the shape and size of the locking plate 2313 to ensure the precise fit between the locking plate 2313 and the second connection portion 11. When the second connection portion 11 is an avoidance groove, the locking plate 2313 may be provided with a guiding inclined surface, and the shape of the avoidance groove is adapted to the shape of the locking plate 2313 to facilitate the fit between the locking plate 2313 and the avoidance groove. The guiding inclined surface can guide the locking plate 2313 to slide smoothly into the avoidance groove, and maintain a stable snap fit in the locked state, thereby enhancing the locking effect between the handle assembly 2 and the base 3. In order to facilitate the processing of the base 3, the second connection portion 11 of the present application is preferably an avoidance hole.

[0069] When the handle 21 rotates to the first state, the user rotates the connecting piece 2311 to drive the locking piece 2313 to rotate to the first position. At this time, part of the locking piece 2313 interferes with the base 3 along the first direction A. Since the movement of the locking piece 2313 along the first direction A is blocked by the base 3, it cannot continue to move along the first direction A, thereby limiting the rotation of the handle 21 around the second direction B, ensuring that the handle 21 remains stable in the locked state and will not be accidentally unlocked due to external force; when the user rotates the connecting piece 2311 to drive the locking piece 2313 to rotate until it is aligned with the avoidance hole, the locking piece 2313 can eliminate the interference with the base 3 through the avoidance hole, and the rotation of the handle 21 around the second direction B can be restored. The user can continue to operate the handle 21 to open or close the upper cover.

[0070] The second locking portion 23 has a second snap-fitting structure 232, which is slidably connected to the handle 21 and is used to connect to the second connecting portion 11 provided on the bracket 1. The second snap-fitting structure 232 slides to a second position to fix the relative position of the bracket 1 and the base 3.

[0071] Specifically, the second clamping structure 232 may include a button, and the handle 21 may be provided with a slide extending along the third direction C. The button is slidably connected to the handle 21 along the third direction C via the slide to ensure the stability of the button sliding.

[0072] The bracket 1 may be provided with a slot along the third direction C to form the second connection portion 11. The shape and size of the slot are adapted to the shape and size of the key, and a guide slope may be provided on the side of the key close to the slot to facilitate the cooperation between the key and the slot. The guide slope can guide the key to slide smoothly into the slot and maintain a stable snap fit in the locked state, thereby enhancing the locking effect between the handle assembly 2 and the bracket 1.

[0073] When the handle 21 rotates to the first state, the user slides the button to the second position. At this time, the button is engaged with the bracket 1 through the slot, thereby limiting the rotation of the handle 21 around the second direction B, ensuring that the handle 21 remains stable in the locked state and will not be accidentally unlocked due to external force; when the user slides the button to disengage from the slot, the button and the bracket 1 are no longer interfered with, and the rotation of the handle 21 around the second direction B is restored. The user can continue to operate the handle 21 to open or close the upper cover.

[0074] The first clamping structure 231 and the second clamping structure 232 can be used independently or in combination.

[0075] In some embodiments, the handle assembly 2 further includes:

[0076] The first elastic component (not shown in the figure) is connected to the first clamping structure 231 and is used to provide an elastic force for the first clamping structure 231 to rotate to the first position.

[0077] Specifically, the first elastic component can be a spring or a torsion spring. In order to make the overall structure more compact, the first elastic component is preferably a torsion spring. The torsion spring is sleeved on the connecting member 2311, and both ends of the torsion spring are fixedly connected to the handle 21. When the connecting member 2311 rotates, the torsion spring generates a torsional moment and provides a rebound force, so that the locking piece 2313 can automatically return to the locked position after unlocking, which is more convenient for the user to operate and ensures the locking effect.

[0078] like Figure 7 and Figure 8 As shown, in some embodiments, the handle assembly 2 further includes:

[0079] The second elastic component 24 is connected to the second clamping structure 232 and is used to provide elastic force for the second clamping structure 232 to slide to the second position.

[0080] Specifically, the second elastic member can be connected to the handle 21 by means of a pin or bonding. The second elastic member provides the second clamping structure 232 with elastic force to automatically rebound to the second position, which simplifies the user's operation and ensures the locking effect. The second elastic member can be made of a spring, elastic rubber, etc. In order to make the overall structure more compact, such as Figure 7 and Figure 8 As shown, in some embodiments, the second elastic component 24 includes a spring, a portion of the second clamping structure 232 extends into the first end of the spring, and the second end of the spring is connected to the handle 21.

[0081] Specifically, a fixing seat or connecting hole adapted to the second end of the spring can be provided inside the handle 21, and the second end of the spring can be inserted into the fixing seat or the mounting hole and fixed by a fastener to ensure that the spring remains stable during the sliding process of the second clamping structure 232.

[0082] like Figure 4 As shown, in some embodiments, the base 3 has a connected plug hole and a receiving space 33; the arc segment extends into the receiving space 33 through the plug hole, the plug hole is adapted to the arc segment, and the plug hole and the receiving space 33 form a first connecting portion 31;

[0083] The accommodating space 33 has a first inner wall, and when the handle 21 rotates to the first state, the arc segment can abut against the first inner wall of the accommodating space 33, so that the relative positions of the bracket 1 and the base 3 are fixed.

[0084] Specifically, when the handle 21 is rotated to the first state, the arc segment can abut against the first inner wall of the accommodating space 33. This abutting design effectively prevents the upper cover from sliding out of the groove of the box body due to external force when the handle 21 is not rotated. That is, the arc segment is abutted against the inner wall of the accommodating space 33 of the base 3, combined with the groove on the box body to fix the relative position of the bracket 1 and the base 3 of the handle 21 in the first state.

[0085] like Figure 4 As shown, in some embodiments, the first end of the arc segment is rotatably connected to the bracket 1, and the arc segment bends from the first end to the second end toward the direction close to the first inner wall. When the handle 21 is rotated to the first state, the second end of the arc segment can abut against the first inner wall of the accommodating space 33.

[0086] Specifically, since the arc segment bends from the first end to the second end toward the direction approaching the first inner wall, when the handle 21 is rotated from the unlocked state to the locked state, the arc segment gradually approaches along its bending direction and finally abuts against the first inner wall. When rotating the handle 21, the user does not need to precisely control the relative position of the arc segment and the first inner wall, and can lock the handle 21 by simply rotating it to a predetermined angle, which is simple and quick to operate.

[0088] Embodiment 2 of the present application provides a server chassis, including: Figures 1 to 6 As shown,

[0089] Upper cover;

[0092] A handle assembly 2, the handle assembly 2 is rotatably connected to the bracket 1;

[0093] The base 3 is connected to the box body; the base 3 is arranged opposite to the bracket 1, and the handle assembly 2 is connected to the base 3 and rotates relative to the bracket 1 to a first state so that the relative position of the bracket 1 and the base 3 can be fixed, so that the upper cover is fixedly connected to the box body.

[0094] The server chassis provided in Example 2 of the present application includes the fixed structure of Example 1, which adopts a bracket 1 connected to the upper cover, and a handle assembly 2 rotatably connected to the bracket 1. Through the rotation of the handle assembly 2, when the handle assembly 2 rotates to the first state, the handle assembly 2 is in a locked state, the relative position of the bracket 1 and the base 3 is fixed, and the bracket 1 and the base 3 will not move relative to each other under the action of external force; when the handle assembly 2 rotates to the second state, the handle assembly 2 is in an unlocked state, and the bracket 1 can move relative to the base 3 to realize the opening or closing of the upper cover. The fixed structure of the present application abandons the limit column structure in the traditional connecting rod sliding structure that is easily affected by the deformation of the upper cover, and adopts a more reliable handle assembly 2 as a locking mechanism, which reduces the risk of unstable connection between the box body and the upper cover due to deformation of the upper cover, and ensures the stability of the connection between the upper cover and the box body.
