Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of electric equipment shell frame, and particularly relates to a multi-degree-of-freedom rotatable pull-out type cabinet under a three-side closed working condition. BACKGROUND

[0002] In the current server cabinet technical field, with the growth of high-density computing and storage demand, multiple servers with different specifications, weights and depths often need to be integrated in a single cabinet. In actual deployment, the number of devices, models and their installation positions in the cradle longitudinal and transverse directions have great flexibility.

[0003] However, the configuration diversity makes the overall center of gravity unpredictable, resulting in asymmetric, directionless eccentric moments, which constitute a continuous static load on the rack structure. This unbalanced stress is not a transient phenomenon, but a long-term existence throughout the life cycle of the device, which accelerates the fatigue of the load-bearing components and reduces the safety and long-term reliability of the device.

[0054] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0055] Please refer to the following: Figures 1 to 9 This invention describes a multi-degree-of-freedom rotatable pull-out cabinet under three-sided enclosed conditions. A multi-degree-of-freedom rotatable pull-out cabinet under three-sided enclosed conditions includes a frame unit 10, a measurement unit 20, and a calibration unit 30. The frame unit 10 includes a housing 101, a pull-out frame 102 slidably disposed within the housing 101, a pull-out structure drively connected to the pull-out frame 102, a rocker arm 103 rotatably connected to the pull-out frame 102, and a fixing structure disposed between the pull-out frame 102 and the rocker arm 103. The pull-out structure is used to drive the pull-out frame 102 to move along a first direction and consists of multiple heavy-duty linear guides. The fixing structure is used to fix the rocker arm 103 and the pull-out frame 102. A heavy-duty hinge is used between the rocker arm 103 and the pull-out frame 102, and the fixing structure is a ball-bearing structure. The measurement unit 20 includes a frame unit 10, a measurement unit 20, and a calibration unit 30. The housing 101 includes a base plate 201, a moving member 202 connected to the base plate 201, and a detection structure connected to the base plate 201. The detection structure includes multiple probes 203 arranged sequentially in the vertical direction. The ends of the probes 203 have a pre-tightening force for moving toward the pull-out bracket 102. The moving member 202 is used to drive the detection structure to move and is a linear module. The calibration unit 30 is located between the housing 101 and the pull-out bracket 102. The calibration unit 30 includes multiple automatic calibration structures. The automatic calibration structure includes a telescopic member 301 and an adsorption member 302 located at the end of the telescopic member 301. The telescopic member 301 extends and retracts in the vertical direction, and the adsorption member 302 is used to fix the pull-out bracket 102 and the telescopic member 301.

[0056] It should be noted that there are at least two measuring units 20, one of which is located on the side of the drawer 102 and the other is located on the back of the drawer 102.

[0057] Optionally, the adsorption component 302 is an electromagnetic component. In this case, the top surface of the pull-out bracket 102 needs to be provided with ferromagnetic material, and the pull-out bracket 102 and the telescopic component 301 are fixed by magnetic adsorption.

[0058] Optionally, the adsorption component 302 is a vacuum suction cup, which fixes the pull-out bracket 102 and the telescopic component 301 by negative pressure adsorption.

[0059] The three-sided enclosed multi-degree-of-freedom rotatable pull-out cabinet provided in this embodiment has a pull-out structure that drives the pull-out frame 102 to move horizontally along the first direction, realizing the overall pushing in and pulling out of the server. The cradle 103 can rotate relative to the pull-out frame 102, which is convenient for multi-angle maintenance. The fixing structure fixes the cradle 103 and the pull-out frame 102 when the cradle 103 does not need to rotate, thereby locking the cradle 103 and the pull-out frame 102 together.

[0060] The measurement unit 20 is responsible for state perception: the moving part 202 drives the detection structure to move, and multiple probes 203 arranged in the vertical direction contact the side wall of the pull-out bracket 102 under the action of the pre-tightening force at their ends. The retraction displacement of the probes 203 is used to accurately detect whether the pull-out bracket 102 is in a vertical state.

[0061] The correction unit 30 is the core of the balance control: multiple automatic correction structures are distributed between the outer shell 101 and the pull-out frame 102. The telescopic components 301 of the automatic correction structures can independently extend and retract in the vertical direction. After the extension and retraction are completed, the adsorption components 302 at the ends of the telescopic components 301 adsorb and fix the pull-out frame 102 at the telescopic end. By measuring the tilt degree and tilt direction of the pull-out frame 102 obtained by the comprehensive measurement unit 20, the extension and retraction of the telescopic components 301 at different positions are controlled, forming uneven but targeted multi-point support at the top of the pull-out frame 102, thereby actively correcting the tilt trend caused by the asymmetrical installation of the equipment, and restoring the entire load to a stable and balanced state.

[0062] Compared to existing technologies, a highly integrated dynamic cabinet system has been constructed. By endowing the cabinet structure with mobility, state awareness, and attitude self-correction capabilities, it comprehensively solves the problem of unpredictable eccentric moments caused by the flexible and variable configuration of internal equipment. This system transforms the traditional cabinet's passive bearing of long-term asymmetric static loads into an active adjustment and dynamic balancing mode. It can effectively counteract the overturning moment generated after equipment installation, thereby significantly reducing the fatigue stress of the load-bearing frame and fundamentally improving the long-term operational safety and structural reliability of the cabinet under complex three-sided enclosed conditions.

[0063] In some embodiments, see Figure 3 and Figure 7 A pressure-bearing unit 40 is provided on the side of the pull-out bracket 102 facing the measuring unit 20.

[0064] The pressure-bearing unit 40 includes a pressure-bearing membrane 401, a winding structure, a clamping member 402, and a transverse moving member 403. The winding structure is located on one side of the pull-out frame 102 and is arranged vertically. The winding structure is used to wind up or unwind the pressure-bearing membrane 401. The winding structure is prior art and will not be described in detail here. The clamping member 402 is slidably disposed on the pull-out frame 102 along a first direction. The clamping member 402 is used to clamp the pressure-bearing membrane 401. The clamping member 402 is prior art and will not be described in detail here. The transverse moving member 403 is connected to the clamping member 402 and is used to drive the clamping member 402 to move. There may be two transverse moving members 403. The two transverse moving members 403 are respectively located at the top and bottom of the outer shell 101. The transverse moving member 403 is a linear module.

[0065] It should be noted that the outer wall of the pull-out bracket 102 has multiple through-holes for heat dissipation.

[0066] During measurement, a pressure-bearing membrane 401 is automatically flattened on the surface of the pull-out frame 102. This structure temporarily transforms the surface with multiple heat dissipation holes into a complete and continuous ideal measurement plane at the moment of detection, ensuring that all probes 203 can obtain stable and reliable contact and consistent retraction displacement data, thereby guaranteeing detection accuracy. After the measurement is completed, the pressure-bearing membrane 401 is quickly rolled up, so that the heat dissipation holes are fully exposed, without affecting the air circulation and heat dissipation efficiency necessary for the operation of the equipment.

[0067] This design enables intelligent and seamless switching between two physical states: temporary planarization during measurement and efficient heat dissipation under normal conditions. It perfectly achieves the environmental conditions necessary for measurement while ensuring that the core heat dissipation function of the cabinet is not compromised.

[0068] In some embodiments, see Figure 8 The pressure unit 40 also includes a pressure airbag 404 disposed on the side of the pressure diaphragm 401 facing the pull-out frame 102 and a pressure pneumatic component connected to the pressure airbag 404. The pressure pneumatic component is used to inflate the pressure airbag 404 or to evacuate the pressure airbag 404. The pressure pneumatic component is an air pump.

[0069] Once the pressure-bearing membrane 401 is unfolded and covers the side wall of the pull-out frame 102, the pressure-bearing pneumatic component is immediately activated, filling the sealed pressure-bearing airbag 404 with gas. The pressure-bearing membrane expands accordingly, and its flexible bladder fills all the gaps between the pressure-bearing membrane 401 and the surface of the pull-out frame 102, "pushing" the pressure-bearing membrane 401 from behind into a taut, flat measuring surface.

[0070] In some embodiments, see Figure 7The pressure unit 40 also includes a push plate 405 disposed on one side of the winding structure and a push-pull member 406 fixed between the push plate 405 and the pull-out frame 102. The push plate 405 extends in the vertical direction, and the push-pull member 406 is used to drive the push plate 405 to move towards or away from the pressure membrane 401. The push-pull member 406 is a telescopic cylinder, an electric cylinder or a hydraulic cylinder.

[0071] By pushing the side of the pressure-bearing membrane 401 with the push plate 405, the side of the pressure-bearing membrane 401 closest to the winding structure and its other side (the side fixed by the clamp 402) are forced to maintain the same distance from the surface of the pull-out frame 102, thereby eliminating the inconsistency in the distance between the two sides of the membrane material and the pull-out frame 102 caused by the winding structure, thus ensuring the detection accuracy of the detection structure.

[0072] In some embodiments, the outer periphery of the push plate 405 is provided with a flexible pad.

[0073] It provides a crucial physical buffer and protection for the active movement of the push plate 405, eliminating the risk of scratches, wear or tear on the membrane surface that may be caused by the edge of the rigid push plate 405 directly contacting and pushing the pressure membrane 401. At the same time, it can also prevent hard collision damage caused by the push plate 405 accidentally contacting the equipment on the pull-out frame 102.

[0074] In some embodiments, the correction unit 30 further includes a feedback structure.

[0075] The feedback structure includes multiple ranging devices, a processing unit, and an alarm. Each ranging device corresponds to a correction structure. The ranging device is used to monitor its own distance to the top surface of the pull-out bracket 102 and output the distance value. The processing unit is connected to the multiple ranging devices. The processing unit is used to receive the distance values ​​and determine whether all the distance values ​​are equal. The processing unit is a computer. The alarm is connected to the processing unit.

[0076] By monitoring the height of the top surface of the pull-out bracket 102 in real time at each calibration point, the system can accurately quantify and evaluate the actual level after automatic calibration. Once the height inconsistency at each point exceeds the allowable tolerance, an alarm is immediately triggered, thus prompting the operator to make manual intervention or the system to adjust itself in a timely manner.

[0077] This design not only ensures the reliability and accuracy of the calibration results, but also prevents hidden structural stress or equipment operation risks caused by inadequate calibration. It places the long-term impact of eccentric torque under continuous and proactive monitoring, greatly improving the safety and intelligent management level of the cabinet's long-term operation.

[0078] In some embodiments, see Figure 9 The correction unit 30 also includes multiple manual correction structures.

[0079] The manual calibration structure includes a calibration seat 303, a calibration airbag 304, and a calibration pneumatic component; the calibration seat 303 is adsorbed and connected to the inner bottom wall of the outer shell 101; the calibration airbag 304 is located on the top surface of the calibration seat 303; the calibration pneumatic component is connected to the calibration airbag 304 and is used to inflate or evacuate the calibration airbag 304, and the calibration pneumatic component is an air pump.

[0080] When manual intervention is required, the operator first places the calibration seat 303 in a predetermined or user-selected position on the bottom wall of the housing 101 and activates the suction device (such as an electromagnet or vacuum suction cup) at its bottom to secure it firmly. Then, the operator controls the calibration pneumatic components (such as a manual air pump or a controlled solenoid valve) to inflate the calibration airbag 304. The airbag inflates, its top bulging and contacting the bottom of the upper pull-out frame 102, lifting that localized area. Conversely, deflating the airbag causes it to contract, reducing the support height at that point. By performing this inflation and deflation operation on multiple manually calibrated structures deployed at different locations and observing the distance measurement feedback or level in real time, the operator can finely adjust the height of each corner or side of the pull-out frame 102 until it is completely level, thus manually eliminating residual overturning torque and effectively supplementing or replacing the automatic calibration system.

[0081] In some embodiments, see Figure 5 and Figure 6 The correction unit 30 also includes a positioning structure.

[0082] The adjustment structure includes an adjustment disk 305, an adjustment component 306, multiple turntables 307, multiple rotating components, and multiple displacement components 308. The adjustment component 306 is fixed between the adjustment disk 305 and the inner top wall of the outer shell 101. The adjustment component 306 extends and retracts in the vertical direction and is a telescopic cylinder, electric cylinder, or hydraulic cylinder. The multiple turntables 307 correspond one-to-one with the automatic correction structure, which is located on the turntables 307. The rotating components are connected to the turntables 307 in a corresponding transmission manner and are used to drive the turntables 307 to rotate in the vertical direction. The multiple displacement components 308 are located one-to-one with the turntables 307 and are used to drive the automatic correction structure to move radially along the turntables 307. The displacement components 308 are linear modules.

[0083] First, the adjusting component 306 acts as a vertical actuator. The telescopic movement of the adjusting component 306 drives the entire adjusting plate 305 to rise and fall as a whole, thereby setting the reference working height of all automatic correction structures installed on it at once, so as to adapt to the overall installation height of different pull-out brackets 102 or equipment.

[0084] Based on this, the displacement member 308 located on each turntable 307 works independently, driving the corresponding automatic correction structure to move precisely in a straight line along the radial direction of the turntable 307, and cooperating with the rotating member to drive the rotation of the turntable 307, thereby enabling the automatic correction structure to adjust its position in the plane corresponding to the turntable 307.

[0085] This collaborative operation of first adjusting the overall height and then adjusting the individual positions allows the system to "tailor-make" a support network with the most effective correction in three-dimensional space for the current load.

[0086] In some embodiments, see Figure 3 and Figure 4 The measuring unit 20 also includes a movable plate 204 and an adjusting member 205; the movable plate 204 is fixedly connected to the slide of the movable member 202; the adjusting member 205 is fixedly connected between the movable plate 204 and the base plate 201, and the extension and retraction direction of the adjusting member 205 is perpendicular to the side wall of the corresponding pull-out bracket 102.

[0087] The spacing between the detection structure and the pull-out bracket 102 is adjustable, thus enabling flexible adaptation to pull-out brackets 102 of different specifications and sizes.

[0088] In some embodiments, see Figure 8 The adsorption component 302 is universally hinged to the telescopic end of the telescopic component 301, and a damping is provided between the adsorption component 302 and the telescopic component 301.

[0089] This design improves the adsorption success rate and long-term connection reliability of the automatic correction structure under complex working conditions. The adsorption component 302 can adaptively adjust its angle to perfectly fit the unevenness or slight tilt that may exist on the bottom surface of the pull-out bracket 102. This ensures that the sealing surfaces of adsorption devices such as vacuum suction cups achieve full-area tight contact, thereby obtaining the maximum and most stable adsorption force and avoiding the risk of insufficient adsorption force, local air leakage or accidental detachment caused by point contact or line contact.

[0090] Meanwhile, the built-in damping effectively suppresses the excessive shaking and swaying of the hinge part at the moment of contact, equipment operation vibration or external force interference, so that the adsorption component 302 can quickly return to stability after being attached. This not only protects the hinge mechanism from impact damage, but also ensures the accuracy and durability of the correction support posture, fundamentally enhancing the static holding ability of the entire correction unit 30 against continuous eccentric torque.

[0091] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
