[0057] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0058] As Figure 1 、 Figure 2 and Figure 22 shown, an embodiment of the present invention provides a tray assembly, which includes a guide rail 10, an outer tray 20, and an inner tray 30. Among them, the outer tray 20 is movably arranged on the guide rail 10 and has a first end 201 and a second end 202 arranged oppositely along the extending direction of the outer tray 20; the inner tray 30 has a head end 301 and a tail end 302 arranged oppositely along the extending direction of the outer tray 20, and the inner tray 30 is movably arranged on the outer tray 20. In the moving direction from the second end 202 to the first end 201, the inner tray 30 has an initial state of being stationary relative to the outer tray 20, a moving state of sliding relative to the outer tray 20, and a flipping state of rotating relative to the outer tray 20. When the inner tray 30 is in the initial state, the head end 301 faces the first end 201, and the tail end 302 faces the second end 202; when the inner tray 30 is in the moving state, the inner tray 30 moves along the extending direction of the outer tray 20, and the tail end 302 moves towards or away from the first end 201; when the inner tray 30 is in the flipping state, the head end 301 is separated from the outer tray 20, and the inner tray 30 flips around the tail end 302.

[0059] Applying the technical solution of the present invention, the hardware is installed on the inner tray 30. When it is necessary to repair or disassemble the hardware, the outer tray 20 and the inner tray 30 can be dragged in the direction from the second end 202 to the first end 201 according to the actual working conditions, so that the inner tray 30 changes from the initial state to the flipped state in sequence. When the first end 301 of the inner tray 30 is separated from the outer tray 20, the inner tray 30 can be flipped downward, which can facilitate the overall exposure of the hardware, and the downward flipping reduces the placement height of the hardware, so as to facilitate the inspection and repair of the hardware by the staff. Compared with the traditional technical solution, the hardware to be repaired can be located outside the cabinet. When it is necessary to repair the hardware, it is not restricted by the space of the cabinet itself and is not interfered by adjacent hardware, effectively improving the convenience of repairing the hardware. Moreover, during the movement of the inner tray 30, the outer tray 20 always supports the inner tray 30, ensuring the stability of the inner tray 30 during the movement. In addition, when the staff pulls the inner tray 30 outward, since the outer tray 20 always supports the inner tray 30, the supporting force applied by the staff to the inner tray 30 can be reduced, and the labor intensity of the staff can be lowered.

[0060] In this embodiment, the direction from the second end 202 to the first end 201 is the outward direction, and the direction from the first end 201 to the second end 202 is the inward direction.

[0061] Specifically, in this embodiment, when the inner tray 30 is in the flipped state, the tail end 302 is located at the first end 201, so as to expand the flipping angle of the inner tray 30 and further improve the convenience of the staff's operation.

[0062] As Figure 1 shown, in this embodiment, there are two guide rails 10, and the two guide rails 10 are respectively located at the two edges in the length direction of the outer tray 20. Combining Figure 16 and Figure 17As shown in the figure, the guide rail 10 includes a baffle 11 and a bearing plate 12. The baffle 11 is located on one side of the outer tray 20 in the length direction and extends along the length direction of the outer tray 20. The bottom end of the baffle 11 is bent towards the center line direction of the outer tray 20 to form the bearing plate 12. The top surface of the bearing plate 12 is provided with ribs 121, and the ribs 121 extend along the length direction of the bearing plate 12. Specifically, during assembly, two guide rails 10 are arranged opposite to each other and fixed on the cabinet, and the outer tray 20 is placed between the two baffles 11, and the bottom of the outer tray 20 contacts the ribs 121. The arrangement of the two guide rails 10 can ensure the stability of the support for the outer tray 20, and further ensure the stability of the outer tray 20 and the inner tray 30 during the moving process. In addition, the arrangement of the baffle 11 can ensure the straightness of the outer tray 20 during the moving process and ensure the stability of the movement of the outer tray 20. The arrangement of the ribs 121 can reduce the friction between the outer tray 20 and the bearing plate 12 and ensure the smoothness of the movement of the outer tray 20. The ribs 121 can be welded to the bearing plate 12 or integrally formed with the bearing plate 12. In this embodiment, the ribs 121 are fixed to the bearing plate 12 by fasteners. After long-term use, the ribs 121 are worn. In this way, it is convenient to replace the ribs 121 and ensure the smoothness of the movement of the outer tray 20.

[0063] Wherein, a limiting component is provided between the outer tray 20 and the guide rail 10, and the limiting component can limit the moving stroke of the outer tray 20 on the guide rail 10. In this embodiment, the maximum displacement of the outer tray 20 can be limited by the limiting component. In this way, during the outward movement of the outer tray 20 and the inner tray 30, the inner tray 30 can be switched from the initial state to the moving state by the limiting component.

[0064] As Figures 3 to 9 shown in the figure, specifically, the limiting component includes a first limiting part 41 and a second limiting part 42. The first limiting part 41 is arranged at the bottom of the guide rail 10; the second limiting part 42 is arranged at the bottom of the outer tray 20, and the second limiting part 42 is located at one end of the first limiting part 41 close to the second end 202, and the second limiting part 42 cooperates with the first limiting part 41 to limit the displacement of the outer tray 20. The above arrangement enables the outer tray 20 not to always move outward synchronously with the inner tray 30. When the outer tray 20 moves to the maximum stroke, the outer tray 20 stops moving, and the inner tray 30 can continue to move outward relative to the outer tray 20.

[0065] In this embodiment, a part of the outer tray 20 is always located on the guide rail 10. Such an arrangement can ensure that the guide rail 10 always has a bearing capacity for the outer tray 20, and further ensure the stability of the outer tray 20. And during the relative movement of the inner tray 30 and the outer tray 20, it can ensure the stability of the support of the outer tray 20 for the inner tray 30, and further ensure the stability of the movement of the inner tray 30.

[0066] Specifically, the first limiting portion 41 is arranged on the bearing plate 12. Pull the outer tray 20 outwards until the second limiting portion 42 abuts against the first limiting portion 41, and the outer tray 20 stops moving outwards. At this time, continue to pull the inner tray 30 outwards, and a relative displacement can occur between the inner tray 30 and the outer tray 20.

[0067] Combined with Figures 3 to 9 、 Figure 17 、 Figure 18 、 Figure 22 As shown, an avoidance hole 203 is formed in the bottom of the outer tray 20. The avoidance hole 203 extends along the length direction of the outer tray 20. The tray assembly further includes a clamping portion 51 and an elastic deformation portion 52. The clamping portion 51 is arranged at the tail end 302. The clamping portion 51 has a first connection end 511 and a clamping end 512 which are oppositely arranged. The first connection end 511 is connected to the tail end 302, and the clamping end 512 is inserted into the avoidance hole 203. The elastic deformation portion 52 is arranged on the bottom of the outer tray 20. The elastic deformation portion 52 has a second connection end 521 and a free end 522 which are oppositely arranged. The second connection end 521 is connected to the bottom of the outer tray 20. Among them, the elastic deformation portion 52 has an original state and a deformed state. When the elastic deformation portion 52 is in the original state, the clamping portion 51 is located on the side of the elastic deformation portion 52 close to the second end 202, and the clamping portion 51 cooperates with and abuts against the elastic deformation portion 52 so that the outer tray 20 and the inner tray 30 can move synchronously. When the elastic deformation portion 52 is in the deformed state, there is an avoidance channel between the free end 522 and the bottom of the outer tray 20. Through this avoidance channel, the clamping portion 51 can be separated from the elastic deformation portion 52. Furthermore, when the inner tray 30 continues to move outwards, the inner tray 30 can move relative to the outer tray 20, and the inner tray 30 is in a moving state.

[0068] Specifically, the avoidance hole 203 is located on the side of the bearing plate 12 close to the center of the outer tray 20. The second connection end 521 is located on the side of the avoidance hole 203 far from the bearing plate 12, and the free end 522 extends to the side of the avoidance hole 203 close to the bearing plate 12.

[0069] By adopting the above technical solution, when pulling the inner tray 30 outwards, an outward acting force is applied to the inner tray 30. Under the action of the clamping portion 51 and the elastic deformation portion 52, the outer tray 20 and the inner tray 30 move outwards together. When the outer tray 20 moves to the maximum stroke, an acting force is applied to the elastic deformation portion 52 to cause the elastic deformation portion 52 to deform, so as to form an avoidance channel between the free end 522 and the bottom of the outer tray 20; continue to pull the inner tray 30 outwards, the clamping portion 51 passes through the avoidance channel, and after the clamping portion 51 passes through the avoidance channel, the elastic deformation portion 52 resumes its original state. At this time, the clamping portion 51 is completely separated from the elastic deformation portion 52, and the inner tray 30 can move relative to the outer tray 20; afterwards, continue to pull the inner tray 30 outwards until the tail end 302 is located at the position of the first end 201, then the inner tray 30 can be turned downwards. After the hardware repair is completed, turn the inner tray 30 upwards until the inner tray 30 is in a horizontal state; then push the inner tray 30 inwards until when the clamping portion 51 moves to the position of the elastic deformation portion 52, apply an acting force to the elastic deformation portion 52 to cause the elastic deformation portion 52 to deform, and the free end 522 and the bottom of the outer tray 20 form an avoidance channel again. Continue to push the inner tray 30 inwards, and the clamping portion 51 passes through the avoidance channel; when the clamping portion 51 passes through the avoidance channel, continue to push the inner tray 30 inwards until the outer tray 20 and the inner tray 30 move to the initial position. The cooperation of the clamping portion 51 and the elastic deformation portion 52 enables the inner tray 30 and the outer tray 20 to not only move synchronously but also move relatively independently, facilitating the staff to pull or push the inner tray 30 and the outer tray 20.

[0070] Specifically, the second limiting portion 42 is located on the side of the elastic deformation portion 52 close to the second end 202, and the first limiting portion 41 and the clamping portion 51 are arranged in a staggered manner in the width direction of the outer tray 20. Such an arrangement avoids interference during the relative movement. Among them, in the direction of the inner tray 30 moving from the second end 202 to the first end 201, when the elastic deformation portion 52 abuts against the first limiting portion 41, the first limiting portion 41 drives the elastic deformation portion 52 to switch from the original state to the deformed state; in the direction of the inner tray 30 moving from the first end 201 to the second end 202, when the clamping portion 51 abuts against the elastic deformation portion 52, the clamping portion 51 drives the elastic deformation portion 52 to switch from the original state to the deformed state.

[0071] With the above settings, during the process of pulling the inner tray 30 and the outer tray 20 outwards, the first limiting portion 41 abuts and cooperates with the elastic deformation portion 52, so that a clearance channel is formed between the free end 522 and the bottom of the outer tray 20. Moreover, during the process of pushing the inner tray 30 inwards, the clamping portion 51 abuts and cooperates with the elastic deformation portion 52, so that a clearance channel is formed between the free end 522 and the bottom of the outer tray 20. In this way, it is not necessary for the staff to apply a force to the elastic deformation portion 52 alone to drive the elastic deformation portion 52 to deform, and the continuity of the movement of the outer tray 20 and the inner tray 30 can be ensured.

[0072] Specifically, there is a receiving space between the second limiting portion 42 and the elastic deformation portion 52, and this receiving space can be used to receive the clamping portion 51 or the first limiting portion 41. When pulling the outer tray 20 and the inner tray 30 outwards, the clamping portion 51 is located in the receiving space. When the elastic deformation portion 52 is in a deformed state, the clamping portion 51 moves out of the receiving space. When the outer tray 20 moves to the maximum stroke, the first limiting portion 41 abuts and limits with the second limiting portion 42, and the first limiting portion 41 is located in this receiving space to limit the outward movement of the outer tray 20 through the cooperation of the first limiting portion 41 and the second limiting portion 42, and limit the inward movement of the outer tray 20 through the cooperation of the first limiting portion 41 and the elastic deformation portion 52. The outer tray 20 is fixed on the guide rail 10, so that it can be more stable when continuing to operate the inner tray 30.

[0073] As Figure 17 and Figure 19 shown, the free end 522 includes a transition section 5221, a horizontal section 5222 and an inclined section 5223. Among them, one end of the transition section 5221 is connected to the second connection end 521, and the other end of the transition section 5221 extends towards the second limiting portion 42; the horizontal section 5222 is connected to the end of the transition section 5221 far from the second connection end 521; one end of the inclined section 5223 is connected to the horizontal section 5222, and both the inclined section 5223 and the transition section 5221 are located on the same side of the horizontal section 5222, and the other end of the inclined section 5223 is inclined downwards towards the direction close to the first end 201. Among them, when the elastic deformation portion 52 is in the original state, the horizontal section 5222 can cooperate with the clamping portion 51 for limiting or cooperate with the first limiting portion 41 for limiting; when the inner tray 30 moves in the direction from the second end 202 to the first end 201, the first limiting portion 41 cooperates with the inclined section 5223 to drive the elastic deformation portion 52 to switch from the original state to the deformed state; when the inner tray 30 moves in the direction from the first end 201 to the second end 202, the clamping portion 51 cooperates with the inclined section 5223 to drive the elastic deformation portion 52 to switch from the original state to the deformed state.

[0074] Further, one end of the horizontal segment 5222 away from the inclined segment 5223 is bent downward to form a vertical segment 5224. In this way, the contact area between the clamping portion 51 and the free end 522 can be increased, ensuring the stability of the clamping portion 51 driving the elastic deformation portion 52 to move synchronously, and when the first limiting portion 41 abuts against the second limiting portion 42 for limiting, the vertical segment 5224 can better cooperate with the first limiting portion 41 for limiting.

[0075] As Figure 3 and Figure 4 shown, the outer tray 20 and the inner tray 30 move outward, and the outer tray 20 and the inner tray 30 move synchronously under the cooperation of the clamping portion 51 and the elastic deformation portion 52. When moving to the position where the elastic deformation portion 52 abuts against the first limiting portion 41, the clamping portion 51 abuts against the horizontal segment 5222 and the vertical segment 5224. As Figure 5 and Figure 6 shown, continue to pull the inner tray 30 outward. Since the absolute position of the first limiting portion 41 does not change, the contact position between the inclined segment 5223 and the first limiting portion 41 gradually transitions from the bottom end of the inclined segment 5223 to the top end of the inclined segment 5223. At this time, the gap between the horizontal segment 5222 and the bottom of the outer tray 20 gradually increases until one end of the horizontal segment 5222 away from the inclined segment 5223 is located below the clamping portion 51. Continue to pull the inner tray 30, and the bottom end of the clamping portion 51 abuts against the top surface of the horizontal segment 5222. After that, the clamping portion 51 drives the horizontal segment 5222 to move synchronously with the clamping portion 51, and the first limiting portion 41 gradually contacts the position where the inclined segment 5223 and the horizontal segment 5222 are connected. Continue to pull the inner tray 30, and the clamping end 512 continues to drive the horizontal segment 5222 to move synchronously with it until both the elastic deformation portion 52 and the clamping portion 51 cross the first limiting portion 41, and when the second limiting portion 42 abuts against the first limiting portion 41, the outer tray 20 stops moving. As Figures 7 to 9 shown, the inner tray 30 continues to move forward, and the clamping portion 51 separates from the inclined segment 5223 until the tail end 302 of the inner tray 30 is located at the position of the first end 201, and then the inner tray 30 can be turned downward.

[0076] As Figure 10 and Figure 11 shown, when it is necessary to reset the inner tray 30 and the outer tray 20, push the inner tray 30 inward until the clamping portion 51 abuts against the inclined segment 5223. As Figure 12 and Figure 13As shown, continue to push the inner tray 30 in the direction of the second end 202. At this time, the contact position between the clamping portion 51 and the inclined section 5223 transitions from the bottom end of the inclined section 5223 to the top end of the inclined section 5223. At this time, the interval between the horizontal section 5222 and the bottom of the outer tray 20 gradually increases until one end of the horizontal section 5222 far from the inclined section 5223 is located below the first limiting portion 41. At this time, the contact between the first limiting portion 41 and the vertical section 5224 fails, and the first limiting portion 41 releases the limit on the outer tray 20. As Figure 14 and Figure 15 shown, continue to push the inner tray 30. Since the contact between the first limiting portion 41 and the inclined section 5223 is released, at this time, the outer tray 20 and the inner tray 30 can move synchronously. After moving a certain distance, the outer tray 20 stops moving after reaching the position, and the inner tray 30 continues to move inward so that the clamping portion 51 slides from the top end of the inclined section 5223 to the horizontal section 5222 and finally separates from the horizontal section 5222. At this time, the clamping portion 51 is located in the accommodation interval again.

[0077] As Figure 17 and Figure 18 shown, the clamping portion 51 is provided with a first mating inclined surface 513 and a second mating inclined surface 514. The first mating inclined surface 513 and the second mating inclined surface 514 are respectively arranged at both ends of the clamping portion 51 along the extension direction of the guide rail 10, and the distance between the first mating inclined surface 513 and the second mating inclined surface 514 gradually decreases along the direction from the first connection end 511 to the clamping end 512. Specifically, the first mating inclined surface 513 is arranged close to the first end 201, and the second mating inclined surface 514 is arranged close to the second end 202. When pulling the inner tray 30 outward, when the top end of the inclined section 5223 abuts against the first limiting portion 41, the first mating inclined surface 513 contacts the top surface of the horizontal section 5222, and the clamping portion 51 drives the elastic deformation portion 52 to move synchronously in the direction of the first end 201. When pushing the inner tray 30 inward, after the second mating inclined surface 514 contacts the inclined section 5223, the clamping portion 51 drives the elastic deformation portion 52 to deform and move it synchronously in the direction of the second end 202. The setting of the first mating inclined surface 513 can ensure the contact area between the first mating inclined surface 513 and the horizontal section 5222, and further ensure the stability of the clamping portion 51 driving the elastic deformation portion 52 to move in the direction of the first end 201; the setting of the second mating inclined surface 514 can ensure the contact area between the second mating inclined surface 514 and the inclined section 5223, and ensure the stability of the clamping portion 51 driving the elastic deformation portion 52 to move in the direction of the second end 202. Moreover, through the above structure, the smoothness of the movement of the clamping portion 51 relative to the elastic deformation portion 52 can be improved, and the wear between the two can be reduced.

[0078] Combined with Figure 17 and Figure 20As shown, the second limiting portion 42 has a third connection end 421 and a limiting end 422 which are arranged opposite to each other. The third connection end 421 is arranged at the bottom of the outer tray 20, and the limiting end 422 is located below the guide rail 10. The limiting end 422 can cooperate with the guide rail 10 to limit. Specifically, the limiting end 422 is located below the bearing plate 12. Since all the loads are concentrated at the position of the first end 201 when repairing or replacing hardware, the setting of the limiting end 422 can prevent the second end 202 from tilting upward, thereby ensuring safety when repairing or replacing hardware.

[0079] like Figure 17 and Figure 21 As shown, the limiting assembly also includes a third limiting portion 43. The third limiting portion 43 is spaced apart from the first limiting portion 41 along the moving direction of the outer tray 20. The third limiting portion 43 is used to limit the displacement of the outer tray 20 in the direction from the first end 201 to the second end 202. The third limiting portion 43 can be set on the guide rail 10 or at other locations. In this embodiment, the third limiting portion 43 is located on the side of the second limiting portion 42 close to the second end 202, and the third limiting portion 43 is set on the cabinet. Figure 22 As shown, the second end 202 is arranged to protrude from the tail end 302, and the third limiting portion 43 is used to abut against the second end 202. When the inner tray 30 is pushed inward, after the clamping portion 51 and the elastic deformation portion 52 pass over the first limiting portion 41, since the second matching inclined surface 514 abuts against the top surface of the inclined section 5223, the outer tray 20 and the inner tray 30 move synchronously toward the second end 202 until the outer tray 20 abuts against the third limiting portion 43, and the outer tray 20 stops moving. At this time, the inner tray 30 continues to be pushed, and the clamping portion 51 passes over the inclined section 5223 and the horizontal section 5222, that is, the clamping portion 51 is separated from the elastic deformation portion 52, and the inner tray 30 and the outer tray 20 are both restored to the initial state.

[0080] like Figure 23 As shown, the tray assembly further includes a fourth limiting portion 60, which is located above the outer tray 20 and is arranged near the first end 201. The fourth limiting portion 60 can be connected to the baffle 11. In this embodiment, the fourth limiting portion 60 is installed on the cabinet. Such a configuration can prevent the outer tray 20 from warping up when the inner tray 30 is pulled outward or pushed inward, thereby ensuring the stability of pulling out or pushing in the inner tray 30 and ensuring the smoothness of sliding of the inner tray 30.

[0081] like Figure 22As shown in the figure, guide posts 71 are provided on the side wall of the inner tray 30, and guide grooves 72 are provided on the side wall of the outer tray 20. The guide posts 71 are movably arranged in the guide grooves 72. The guide grooves 72 include a straight section 721 and an arc section 722, and the arc section 722 is arranged close to the first end 201. Specifically, at the first end 201, the end of the side wall of the outer tray 20 protrudes from the bottom wall of the outer tray 20. The arc section 722 has a starting end and a terminating end arranged oppositely. The starting end is communicated with the straight section 721, and the terminating end extends to the end of the side wall of the outer tray 20. Such an arrangement can ensure the relative movement between the inner tray 30 and the outer tray 20, and ensure the smoothness of the flipping of the inner tray 30.

[0082] As Figures 24 to 29 shown in the figure, another embodiment of the present application provides a cabinet, which includes a frame body 81, a door panel 82 and the tray assembly described above. The tray assembly is installed on the frame body 81, the door panel 82 is located on the outer periphery of the frame body 81 and installed on the frame body 81, and a ring-shaped sealing strip 83 is provided on the side of the door panel 82 close to the frame body 81. By providing the sealing strip 83, the overall sealing effect of the cabinet can be ensured.

[0083] Specifically, in this embodiment of the cabinet, a power module, an expansion area, a control module and a power distribution module are sequentially arranged from top to bottom. Among them, the power module can place products such as UPS and battery modules, and the expansion area can be configured with different numbers of UPS or battery modules according to customer requirements; the control module can install various control switches and control signal interfaces and other devices according to actual needs; the power distribution module is also equipped with different wiring devices according to actual needs, such as copper bars, wiring terminals, etc. In this way, the area can be reasonably divided into modules, modular design can be realized, and the utilization rate of the frame body 81 can be ensured.

[0084] Installing the hardware on the frame body 81 through the tray assembly in the present application can separate the hardware from the frame body 81 when repairing and replacing the hardware, ensuring the convenience of repairing the hardware.
