[0039] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] Please refer to Figures 1 to 7 , Figure 1 A schematic diagram of the structure of a computer room cabinet in a first direction provided in an embodiment of the present application; Figure 2 A schematic diagram of the structure of the lighting travel switch provided in the embodiment of the present application; Figure 3 A schematic diagram of the partial structure of a machine room cabinet at a spring door device provided in an embodiment of the present application; Figure 4 A schematic diagram of the structure of a computer room cabinet in a second direction provided in an embodiment of the present application; Figure 5 A schematic diagram of the structure of a computer room cabinet in a third direction provided in an embodiment of the present application; Figure 6 A schematic diagram of the structure of a self-resetting travel switch provided in an embodiment of the present application; Figure 7 This is a schematic diagram of the structure of the computer room cabinet in the fourth direction provided in an embodiment of the present application.

[0041] Please refer to Figure 1 and Figure 3The present application provides a computer room cabinet, comprising a cabinet body 1 having a cabinet body 11 and a cabinet door 12, a smoke sensor arranged in the cabinet body 11, an electric-driven locking device arranged between the cabinet body 11 and the cabinet door 12, and a spring-loaded door device 3 arranged between the cabinet body 11 and the cabinet door 12; the aforementioned smoke sensor is arranged in the cabinet body 11, specifically, on the inner side of the cabinet top plate near the cabinet door 12, for monitoring the fire inside the cabinet body 11, and can send a signal when smoke appears in the cabinet body 11; the aforementioned electric-driven locking device is arranged between the cabinet body 11 and the cabinet door 12, and can be used to lock the cabinet body 11 and the cabinet door 12, so that the cabinet body 1 is in a closed state, and of course, the cabinet body 11 and the cabinet door 12 can also be unlocked to put the cabinet body 1 in an open state; the aforementioned spring-loaded door device 3 is arranged between the cabinet body 11 and the cabinet door 12, and can use its own elastic force to drive the cabinet body 11 and the cabinet door 12 to move relative to each other, so as to open the cabinet door 12.

[0042] In this embodiment, the cabinet body 1 includes a cabinet body 11 and a cabinet door 12, the cabinet door 12 is rotatably connected to the cabinet body 11, and the rotating shaft of the cabinet door 12 is distributed along the height direction of the cabinet body 1. For example, the cabinet body 1 is placed vertically in the machine room, and the aforementioned rotating shaft is arranged on one side of the cabinet body 11 along the width direction. At the same time, the aforementioned rotating shaft is distributed vertically. It can be seen that the cabinet door 12 can be opened and closed by rotating around the rotating shaft relative to the cabinet body 11.

[0043] In this embodiment, the door-springing device 3 is arranged between the cabinet body 11 and the cabinet door 12, and can be driven by its own elastic force, so that the cabinet door 12 rotates around the rotating shaft relative to the cabinet body 11, thereby realizing opening and closing the cabinet door 12. The aforementioned door-springing device 3 may include a mounting seat 31 and an elastic energy storage part 32 arranged on the mounting seat 31; the mounting seat 31 can slide along the width direction of the cabinet body 1 and be locked to one of the cabinet body 11 and the cabinet door 12, and the elastic energy storage part 32 can abut against the other of the cabinet body 11 and the cabinet door 12. For example, the mounting seat 31 is slidably connected to the cabinet body 11 along the width direction of the cabinet body 1 and can be locked at any position of the sliding path. At the same time, one end of the elastic energy storage part 32 is connected to the mounting seat 31 and the other end abuts against the cabinet door 12; wherein the elastic energy storage part 32 is constructed to be in a compressed energy storage state when the cabinet body 11 and the cabinet door 12 are locked with each other.

[0044] Since the mounting seat 31 slides along the width direction of the cabinet body 1 and is locked to the cabinet body 11 or the cabinet door 12, and the rotating shaft of the cabinet door 12 is distributed along the height direction of the cabinet body 1, the distance between the mounting seat 31 and the rotating shaft is adjustable.

[0045] by Figure 1 For example, Figure 1 The up and down direction is the height of the cabinet body 1, Figure 1The left and right directions are the width directions of the cabinet body 1, the rotating shaft is arranged at the right edge of the cabinet body 1, and the mounting seat 31 is arranged between the cabinet body 11 and the cabinet door 12. Usually, the mounting seat 31 is located at the top edge of the cabinet body 11. When the mounting seat 31 slides toward the right along the width direction of the cabinet body 1, the distance between the spring door device 3 and the rotating shaft is reduced. On the contrary, when the mounting seat 31 slides toward the left along the width direction of the cabinet body 1, the distance between the spring door device 3 and the rotating shaft is increased. In the above example, changing the distance between the spring door device 3 and the rotating shaft can adjust the effect of the spring door device 3 applied to the cabinet door 12 when opening the cabinet door 12. For example, when the distance between the spring door device 3 and the rotating shaft is small, the elastic force applied by the spring door device 3 to the cabinet door 12 causes the cabinet door 12 to open with a small amplitude, and when the distance between the spring door device 3 and the rotating shaft is large, the elastic force applied by the spring door device 3 to the cabinet door 12 causes the cabinet door 12 to open with a large amplitude. Based on the above settings, the operator can adjust the installation position of the door pop-up device 3 according to the position of the cabinet body 1 and its cabinet door 12 to ensure that the cabinet door 12 can be automatically opened with a suitable opening range under the action of the door pop-up device 3.

[0046] In this embodiment, the smoke sensor is arranged in the cabinet body 11, the electric-driven locking device 2 is arranged between the cabinet body 11 and the cabinet door 12, and the electric-driven locking device 2 is configured to be powered off when the smoke sensor collects smoke. In addition, the electric-driven locking device 2 is coupled to the smoke sensor. It can be seen that when the smoke sensor detects smoke inside the cabinet body 11, the electric-driven locking device 2 can perform a power-off operation according to the monitoring signal of the smoke sensor. After the electric-driven locking device 2 is powered off, the locked state of the cabinet body 11 and the cabinet door 12 is released, so that the cabinet body 11 and the cabinet door 12 can be separated from each other; on the contrary, when the smoke sensor does not detect smoke inside the cabinet body 11, the electric-driven locking device 2 is in a powered-on state, and can lock the cabinet body 11 and the cabinet door 12 to prevent the cabinet body 11 and the cabinet door 12 from being separated from each other. As can be seen from the foregoing, a door spring device 3 is provided between the cabinet body 11 and the cabinet door 12. Once the electric drive locking device 2 is powered off, the door spring device 3, which is originally in a compressed energy storage state, releases its elastic force, and this elastic force can push the cabinet door 12 to rotate relative to the cabinet body 11, thereby opening the cabinet door 12. The electric drive locking device 2 can be an electromagnetic lock or other element.

[0047] In summary, the computer room cabinet provided in the present application utilizes a smoke sensor, an electric-driven locking device 2 and a pop-up door device 3 to realize smoke monitoring and automatic door opening, thereby realizing rapid opening of the cabinet door 12 when smoke occurs inside the cabinet body 11, facilitating the entry of fire-fighting gases and other fire-fighting materials in the computer room into the cabinet body 11, controlling the smoke and fire situation of the computer room cabinet, and eliminating the smoke and fire points of the computer room cabinet; the computer room cabinet provided in the present application can flexibly adjust the specific installation position of the pop-up door device 3 on each cabinet body 1 according to parameters such as the specific distribution position of the cabinet body 1 in the computer room, the relative position relationship between different cabinet bodies 1, and the relative position relationship between the cabinet body 1 and the fire-fighting equipment in the computer room, so that the pop-up door device 3 can drive the cabinet door 12 to open to an appropriate opening to ensure that fire-fighting gases and other fire-fighting materials enter the cabinet body 11, and can also prevent the cabinet door 12 from colliding or rebounding due to excessive opening, thereby avoiding affecting the actual opening effect of the cabinet door 12, avoiding noise, and avoiding damage to the cabinet door 12 or other equipment in the computer room.

[0048] The computer room cabinet provided in this application is further described below in conjunction with the accompanying drawings and implementation methods.

[0049] Please refer to Figure 1 and Figure 5 In some embodiments, the machine room cabinet provided by the present application further includes a cabinet lock 5; the cabinet lock 5 is arranged between the cabinet body 11 and the cabinet door 12, and is used to control the power-on and power-off states of the electric drive locking device 2. In other words, the electric drive locking device 2 is connected to the cabinet lock 5, and the electric drive locking device 2 is configured to be powered off when the cabinet lock 5 is opened. In this embodiment, the operator can use the cabinet lock 5 to manually adjust the power-on and power-off states of the electric drive locking device 2. For example, when the entire machine room cabinet is powered on normally, when the operator opens the cabinet lock 5, the cabinet lock 5 powers off the electric drive locking device 2. After the electric drive locking device 2 is powered off, the locking state of the cabinet body 11 and the cabinet door 12 is released, so that the cabinet body 11 and the cabinet door 12 can be separated from each other. On the contrary, when the operator does not operate the cabinet lock 5, the electric drive locking device 2 is not controlled by the cabinet lock 5, and the power-on and power-off states of the electric drive locking device 2 depend on the monitoring signal of the smoke sensor.

[0050] In the above embodiment, the electric-driven locking device 2 can draw power through the sunroof control box; the aforementioned sunroof control box is linked with the smoke sensor. When the smoke sensor transmits a fire alarm signal to the sunroof control box, the relay in the sunroof control box will cut off the circuit of the electric-driven locking device 2, thereby realizing remote automatic door opening.

[0051] In the above embodiment, there are two ways to open the cabinet door 12 of the computer room cabinet: first, the electric drive locking device 2 and the door spring device 3 automatically open the cabinet door 12 according to the monitoring signal of the smoke sensor; second, the operator manually operates the cabinet lock 5 to cut off the power of the electric drive locking device 2, and then the door spring device 3 opens the cabinet door 12 or the door spring device 3 and the operator jointly open the cabinet door 12. Obviously, when smoke and fire occur inside the cabinet body 11, the cabinet door 12 of the computer room cabinet is automatically opened in the first cabinet door 12 opening method mentioned above, which is convenient for the fire fighting equipment in the computer room to extinguish smoke and fire on the cabinet body 11 and its components; when there is no smoke and fire inside the cabinet body 11, the cabinet door 12 of the computer room cabinet is manually opened in the second cabinet door 12 opening method mentioned above, which is convenient for the operator to observe and maintain the cabinet body 11 and its components.

[0052] On the basis of the above-mentioned embodiments, the machine room cabinet provided in the present application also includes a lighting device; the lighting device is arranged in the cabinet body 11, the lighting device is linked to the switch of the cabinet lock 5, and the lighting device is constructed to be powered on and illuminated when the cabinet lock 5 is opened. The switch linkage of the lighting device and the cabinet lock 5 specifically means that the lighting device is constructed to be turned on when the cabinet lock 5 is opened and turned off when the cabinet lock 5 is closed. Based on the aforementioned linkage relationship between the lighting device and the cabinet lock 5, when the operator manually opens the cabinet door 12, the cabinet lock 5 can not only cut off the power to the electric drive locking device 2, but also turn on the lighting device, so that the lighting device provides lighting for the interior of the cabinet body 11, which is convenient for the operator to observe and maintain the components inside the cabinet body 11.

[0053] In the above embodiment, in addition to being linked with the cabinet lock 5, the lighting device can also be linked with the electric drive locking device 2. For example, the lighting device is configured to be turned off when the electric drive locking device 2 is powered on and turned on when the electric drive locking device 2 is powered off. Based on the aforementioned linkage relationship between the lighting device and the electric drive locking device 2, no matter the cabinet door 12 is opened in the first cabinet door 12 opening method mentioned above or in the second cabinet door 12 opening method mentioned above, the lighting device will be turned on when the cabinet door 12 is opened to provide lighting for the interior of the cabinet body 11.

[0054] For reference Figure 1 and Figure 2 In order to realize the linkage between the lighting device and the cabinet lock 5 or the electric drive locking device 2, the cabinet door 12 can be provided with a lighting travel switch 6, which can be connected to the cabinet lock 5 or the electric drive locking device 2. When the cabinet door 12 is opened, the lighting travel switch 6 is turned on, and the lighting device, such as a lighting lamp, is powered on. When the cabinet door 12 is closed, the lighting travel switch 6 is turned off, and the lighting lamp is powered off.

[0055] The lighting device can serve the early server rack and the later operation and maintenance cabinet. The specific structure of the lighting device can refer to the relevant settings in the prior art. The specific installation position of the lighting device inside the cabinet body 11 includes but is not limited to the internal top surface of the cabinet body 11. According to the actual installation position of various electrical components in the cabinet body 11, the lighting device can also be set on the internal rear side, internal left and right sides of the cabinet body 11, etc.

[0056] For reference Figure 1 and Figure 6 On the basis of some of the embodiments provided above, the machine room cabinet provided in the present application also includes a self-resetting travel switch 7; the self-resetting travel switch 7 is arranged between the cabinet body 11 and the cabinet door 12, and the electric drive locking device 2 is connected to the cabinet lock 5 through the self-resetting travel switch 7.

[0057] The self-resetting travel switch 7 is arranged between the cabinet body 11 and the cabinet door 12. At the same time, the self-resetting travel switch 7 is arranged between the cabinet lock 5 and the electric drive locking device 2. The cabinet lock 5, the self-resetting travel switch 7 and the electric drive locking device 2 are connected in a transmission manner. The operator can drive the self-resetting travel switch 7 to operate through the cabinet lock 5, so that the self-resetting travel switch 7 cuts off the power to the electric drive locking device 2. As for the specific structure of the self-resetting travel switch 7, the specific connection method of the cabinet lock 5, the self-resetting travel switch 7 and the electric drive locking device 2, please refer to Figure 6 , and reference may also be made to the relevant settings in the prior art.

[0058] For reference Figures 1 to 5 In some embodiments, the machine room cabinet provided by the present application includes a cabinet body 11 and a cabinet door 12, and the cabinet door 12 is provided with a handle 4, which is connected to the cabinet lock 5 and is used to operate the cabinet lock 5. Usually, the handle 4 and the cabinet lock 5 are respectively arranged on the inner and outer sides of the cabinet door 12, for example, the handle 4 is arranged on the outer ear of the cabinet door 12, and the cabinet lock 5 is arranged on the inner side of the cabinet door 12. The operator can drive the cabinet lock 5 to operate through the handle 4 to open and close the cabinet lock 5. In this embodiment, the handle 4, on the one hand, serves as the action input end of the cabinet lock 5, which is convenient for the operator to operate the cabinet lock 5 arranged on the inner side of the cabinet door 12, and on the other hand, serves as an auxiliary structure for the operator to push and pull the cabinet door 12, which is convenient for the operator to drive the cabinet door 12 to rotate around the rotating shaft. In the aforementioned example, when the cabinet lock 5 is driven to operate by the handle 4, the action principle of the handle 4 includes but is not limited to rotation and pressing.

[0059] like Figure 1As shown, on the basis of the above-mentioned embodiments, the machine room cabinet provided by the present application is provided with a cabinet lock 5 and two electric-driven locking devices 2; the two electric-driven locking devices 2 are arranged between the cabinet body 11 and the cabinet door 12 and are respectively located at the two ends of the cabinet door 12 along the height direction; the cabinet lock 5 is located in the middle of the cabinet door 12 along the height direction. In the aforementioned example, the cabinet body 11 and the cabinet door 12 are locked to each other by two electric-driven locking devices 2, which is adapted to the shape and size of the common cabinet body 1, and can ensure the locking effect of the electric-driven locking device 2 on the cabinet body 11 and the cabinet door 12; in the aforementioned example, from the height direction of the cabinet body 1, the cabinet lock 5 is arranged between the two electric-driven locking devices 2, which is adapted to the relative height of the operator and the cabinet body 1, and is convenient for the operator to operate the cabinet lock 5 or the handle 4 connected to the cabinet lock 5.

[0060] In some embodiments, the machine room cabinet is provided with a spring door device 3, which includes a mounting seat 31 and an elastic energy storage portion 32. Figure 1 and Figure 3 , the elastic energy storage part 32 may include a torsion spring. Generally, the elastic energy storage part 32 includes a plurality of torsion springs, which are arranged side by side between the cabinet body 11 and the cabinet door 12. In other words, the torsion springs are arranged in parallel.

[0061] In addition, in some embodiments, the computer room cabinet provided in the present application also includes a cabinet door limit device for maintaining the maximum opening of the cabinet door 12; the cabinet door limit device is arranged between the cabinet body 11 and the cabinet door 12. When the cabinet door 12 is opened to the maximum opening, the cabinet door limit device connects the cabinet door 12 and maintains the current opening of the cabinet door 12 to prevent the cabinet door 12 from shaking, thereby avoiding the cabinet door 12 from generating noise due to shaking or affecting the actual opening of the cabinet door 12.

[0062] The above-mentioned cabinet door limiting device can utilize magnetic attraction, negative pressure attraction, snap force and other forces to position the cabinet door 12 to its maximum opening. For example, the cabinet door limiting device is located on the outside of the cabinet body 1 and is arranged on the cabinet body 11. At the same time, the cabinet door limiting device is located at one of the end points of the flipping trajectory of the cabinet door 12. When the cabinet door 12 flips open relative to the cabinet body 11 around the rotating axis, the cabinet door 12 gradually approaches the cabinet door limiting device along its flipping trajectory. Once the cabinet door 12 flips to the maximum opening, the cabinet door 12 and the cabinet door limiting device contact each other, and the cabinet door limiting device can magnetically absorb the cabinet door 12 to prevent the cabinet door 12 from continuing to rotate, thereby maintaining the current opening of the cabinet door 12. Of course, in the aforementioned embodiment, the cabinet door limiting device has magnetic attraction performance, and the cabinet door 12 is provided with a magnetic attraction portion matching the cabinet door limiting device.

[0063] For reference Figure 5 and Figure 7In some embodiments, the computer room cabinet provided in the present application includes a cabinet body 11 and a cabinet door 12, wherein the cabinet body 11 is provided with a guide fan, which can drive the gas to flow inside and outside the cabinet body 11. For example, the guide fan can drive the fire-fighting gas in the computer room to flow inside and outside the cabinet body 11, ensuring that the fire-fighting gas can flow into and out of the cabinet body 1 efficiently and quickly after the cabinet door 12 is opened, so as to perform fire control on the smoke-generating parts or fire-generating parts in the cabinet body 1.

[0064] In the above embodiment, the air guide fan may include an air intake fan and an air exhaust fan; the air supply directions of the air intake fan and the air exhaust fan are opposite, for example, the air intake fan is configured to suck air into the cabinet body 11, and the air exhaust fan is configured to exhaust the air in the cabinet body 11 to the outside. Figure 1 For example, Figure 1 The up and down direction is the height of the cabinet body 1, Figure 1 The left and right directions are the width directions of the cabinet body 1, and the rotating shaft is arranged at the right edge of the cabinet body 1; in the above example, the air inlet fan is close to the rotating shaft, which is conducive to sucking as much external gas, such as firefighting gas, into the internal right cavity of the cabinet body 11 as possible when the cabinet door 12 is not opened enough, so as to avoid affecting the firefighting effect inside the cabinet body 11 due to the insufficient opening of the cabinet door 12. At the same time, the exhaust fan is far away from the rotating shaft, which is conducive to allowing external gas, such as firefighting gas, to be fully diffused in the cabinet body 11 before being discharged. Among them, the reasons for the insufficient opening of the cabinet door 12 include but are not limited to abnormalities in the door spring device 3, abnormalities in the connection between the cabinet door 12 and the cabinet body 11, and the special distribution position of the cabinet body 1 in the machine room.

[0065] Based on the above embodiments, Figure 7 As shown, the cabinet body 11 is provided with an exhaust mesh plate; the exhaust mesh plate has holes, which can provide a certain degree of air circulation performance for the cabinet body 1 when the cabinet door 12 is not opened, dissipate heat and cool the cabinet body 1, and can also improve the flow performance of the fire-fighting gas inside and outside the cabinet body 1 when the cabinet door 12 is opened.

[0066] The exhaust mesh plate and the cabinet door 12 are respectively located on different sides of the cabinet body 11. For example, the cabinet door 12 is arranged on the front side of the cabinet body 11, and the exhaust mesh plate is arranged on the rear side of the cabinet door 12. In this case, the exhaust mesh plate and the cabinet door 12 are distributed on opposite sides of the cabinet body 11. For another example, the exhaust mesh plate is arranged on at least one of the left side and the right side of the cabinet body 11, and the cabinet door 12 is arranged on the front side of the cabinet body 11. In this case, the exhaust mesh plate and the cabinet door 12 are distributed on the adjacent side of the cabinet body 11.

[0067] In summary, the computer room cabinet provided in the present application can automatically open the door and accurately adjust and maintain the opening of the cabinet doors 12 of different cabinet bodies 1 when smoke or fire occurs inside the cabinet body 1, thereby utilizing the fire-fighting gas provided by the computer room to carry out fire prevention and control inside the cabinet body 1, thereby improving fire-fighting efficiency and controlling fire-fighting costs, without the need for on-site operation by operation and maintenance personnel, and improving personnel safety.
