Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0048] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back...), the directional indications are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0049] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the utility model, the descriptions of "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model.

[0050] The power supply system uses the power distribution cabinet as the hardware carrier, and installs the power supply and distribution equipment by arranging three-way wiring in the power distribution cabinet. The stability and safety of the power supply system are crucial to the smooth operation of the data center. Therefore, the distribution cabinet door needs to be completely closed and locked after each routine operation and maintenance to ensure the protection of the parts and lines in the distribution cabinet and reduce the risk of line short circuit, aging and human damage.

[0051] However, the existing cabinet door is hinged to the cabinet body at one end and snap-fitted at the other end to form a closure for the cabinet body. This closure method makes the cabinet door easily pulled open by external force, resulting in exposure of parts and circuits inside the distribution cabinet. Even if the cabinet door and the cabinet body are connected by a lock tongue and a lock buckle, the spring on the lock tongue loses its flexibility in expansion and contraction during long-term use, resulting in the lock tongue and the lock buckle being unlocked and difficult for maintenance personnel to detect, so that the cabinet door is easily opened when the locking structure is unlocked, affecting the protection effect of the parts and circuits inside the cabinet.

[0052] In order to solve the above problems, the utility model provides a cabinet door locking detection device and a power supply cabinet 100. Figures 1 to 14 This is a specific embodiment of the power supply cabinet 100 provided by the utility model.

[0053] See also Figures 1 to 14The cabinet door locking detection device is used for a power supply cabinet 100, and the power supply cabinet 100 includes a cabinet body 1 and a cabinet door 2. One side of the cabinet door 2 is rotatably installed on the cabinet body 1. The cabinet door locking detection device includes: a locking component and a distance detection device. The locking component includes a locking part and a matching part, one of which is used to be set on the cabinet door 2, and the other is set on the cabinet body 1 of the power supply cabinet. The locking part is used to cooperate with the matching part to lock the cabinet door 2 and the cabinet body 1 of the power supply cabinet 100. The distance detection device includes a detection part and a sensing part, one of which is used to be set on the cabinet door 2, and the other is set on the cabinet body 1 of the power supply cabinet. The detection part is used to send a detection signal toward the sensing part and receive a feedback signal from the sensing part.

[0054] In the technical solution provided by the utility model, by setting the distance detection device, when the cabinet door locking detection device is installed on the power supply cabinet 100, it can detect the distance between the cabinet door 2 and the cabinet body 1 to determine whether the cabinet door 2 is locked, thereby avoiding the occurrence of the phenomenon of the cabinet door 2 being locked in vain.

[0055] It should be noted that the specific implementation forms of the locking part and the matching part are not limited, and can be in the form of a locking rod and a lock groove, or in the form of a locking hook and a locking rod, etc., which are not limited here. One of the locking part and the matching part is used to be set on the cabinet door 2, and the other is set on the cabinet body 1 of the power supply cabinet. The locking part can be set on the cabinet door 2 and the matching part can be set on the cabinet body 1, or the locking part can be set on the cabinet body 1 and the matching part can be set on the cabinet door 2. This is not limited here. The specific implementation forms of the detection part and the sensing part are not limited, and can be an infrared ranging device, or a combination of a displacement sensor 33 and a signal receiver 45, etc., which are not limited here. One of the detection part and the sensing part is used to be set on the cabinet door 2, and the other is set on the cabinet body 1 of the power supply cabinet. The detection part can be set on the cabinet door 2 and the sensing part can be set on the cabinet body 1, or the detection part can be set on the cabinet body 1 and the sensing part can be on the cabinet door 2. This is not limited here.

[0056] The detection part is used to send a detection signal toward the sensing part and receive a feedback signal from the sensing part, which means that the detection part sends a detection signal toward the sensing part, and the sensing part sends a feedback signal to the detection part after receiving the detection signal. Then, the distance between the cabinet door 2 and the cabinet body 1 can be calculated according to the time interval between the sending time of the detection signal and the receiving time of the feedback signal, so as to judge whether the cabinet door 2 is locked. When it is detected that the cabinet door 2 is not locked, an alarm can be sounded through the alarm device on the power supply cabinet 100 to remind the user that the cabinet door 2 is not locked, so that the user can check, thereby avoiding the occurrence of empty locks. Of course, other reminders can also be used, such as information prompts to the user's communication equipment, etc., which are not limited here.

[0057] Further, it is understandable that detection is not required at all times. Therefore, the detection unit includes a displacement sensor 33, and the distance detection device also includes a switch element electrically connected to the displacement sensor 33. The switch element is used to turn on the displacement sensor 33 when closed, and disconnect the displacement sensor 33 when opened. In the scheme of this embodiment, the switch element is set so that when the distance detection device is required to perform detection, the displacement sensor 33 is turned on to enable it to send and receive signals. When the distance detection device is not required to perform detection, the switch element is opened to disconnect the displacement sensor 33.

[0058] It should be noted that the opening and closing of the switch element may be manually controlled, may be automatic, may be linked with other components, etc., which is not limited here.

[0059] In one embodiment, the locking portion includes a rotating member, which has an active stroke that moves toward or away from the mating portion, and the switch member includes a conduction button 37 arranged in the active stroke of the rotating member, so that when the rotating member and the mating component are engaged, the rotating member presses the conduction button 37 to cause the displacement sensor 33 to send a signal.

[0060] In the scheme of this embodiment, since the locking part includes a rotating part, the rotating part is rotated toward the matching part to achieve locking cooperation between the locking part and the matching part, and when the rotating part is rotated away from the matching part, the cabinet door 2 and the cabinet body 1 are unlocked, and the conduction button 37 is set on the active stroke of the rotating part. When the rotating part and the matching component are snap-fitted, the rotating part presses the conduction button 37 to make the displacement sensor 33 send a signal, that is, the cabinet door 2 is turned on when the opening of the cabinet body 1 is closed, and the displacement sensor 33 is not turned on when the cabinet door 2 is opened.

[0061] It is understandable that the rotating member may include only a locking rod, so that the locking rod can simultaneously realize the pressing of the conduction button 37 and the locking cooperation with the matching portion. Of course, the locking hook 17 can also be provided to realize the locking and the pressing member 19 can be provided to realize the conduction pressing. This is not limited here. When only the locking rod is included, the overall volume of the locking rod will be made relatively large. Therefore, the locking portion also includes a mounting plate 13 and a lock core 12 rotatably mounted on the mounting plate 13, and the matching portion includes a snap-fit ​​matching member 35. The rotating part includes: a connecting column 16, a locking hook 17 and a pressing member 19, and the connecting column 16 is fixedly connected to the lock core 12; one end of the locking hook 17 is fixedly installed on the connecting column 16, and the other end is formed with a locking hook 18, and the locking hook 18 is used to engage with the snap-fitting member 35; one end of the pressing member 19 is fixedly installed on the connecting column 16, and the pressing member 19 is used to press the conduction button 37 when the locking hook 17 is engaged with the snap-fitting member 35.

[0062] In the technical solution of this embodiment, the lock core 12 is fixedly connected to the connecting column 16, so that when the lock core 12 rotates, the connecting column 16 and the lock core 12 rotate synchronously, and the locking hook 17 and the pressing member 19 are both installed on the connecting column 16. Therefore, the locking hook 17 and the pressing member 19 rotate synchronously with the connecting column 16, and when rotating toward the snap-fitting fitting 35, the lock hook 18 snaps and cooperates with the snap-fitting fitting 35, thereby locking the lock. The cabinet door 2 and the cabinet body 1, the pressing piece 19 synchronously presses the conduction button 37, and when rotating away from the snap-fitting piece 35, the lock hook 18 and the snap-fitting piece 35 are separated, thereby unlocking the cabinet door 2, and the pressing piece 19 releases the pressing state of the conduction button 37. In this way, the locking hook 17 realizes the locking and unlocking of the cabinet door 2, and the pressing piece 19 realizes the pressing of the conduction button 37. The two do not interfere with each other, which improves the stability of their respective functions.

[0063] Furthermore, in order to realize the rotational installation of the lock core 12 , a bearing 11 is provided between the lock core 12 and the mounting plate 13 .

[0064] See also Figure 2 The shape of the lock hole 15 of the lock core 12 is not limited, and can be a "straight" lock hole or a "M"-shaped lock hole. In one embodiment, the lock hole 15 of the lock core 12 is a special lock hole, and the special-shaped lock hole is a "wood"-shaped lock hole. Compared with other lock holes, the key structure corresponding to the "wood"-shaped lock hole is more complicated, thereby improving security.

[0065] See also Figure 4 The snap-fit ​​fitting 35 includes a mounting section and a snap-fit ​​section 36 which are sequentially arranged. The mounting section is used to be fixedly mounted to the cabinet 1. The diameter of the snap-fit ​​section 36 is smaller than half of the diameter of the lock hook 18. The snap-fit ​​fitting 35 is a cylindrical rod with a smooth surface for easy adaptation to the lock hook 18.

[0066] The pressing member 19 is provided with a pressing portion 20 corresponding to the conduction button 37 , and an arc surface is provided on the circumference of the pressing portion 20 . Specifically, the pressing portion 20 is provided in a columnar shape, and a rounded surface is provided on the surface of the columnar body, so as to improve the stability of pressing the conduction button 37 .

[0067] Furthermore, when it is detected that the cabinet door 2 is not locked, it is necessary to inform the user. Therefore, the cabinet door locking detection device also includes an alarm device, and the alarm device is communicatively connected to the distance detection device to alarm when the distance detection device detects that the cabinet door 2 is not locked, so that when the distance detection device detects that the cabinet door 2 is not locked, the alarm device is notified to alarm.

[0068] Specifically, in one embodiment, the alarm device includes a safety warning light 4 and a voice alarm component 10, the voice alarm component 10 is a buzzer or a speaker that can be inserted into a memory card, the safety warning light 4 is an embedded LED light emitting diode, and the voice alarm component 10 alarms through sound signals to increase the vigilance of maintenance personnel.

[0069] In order to improve the alarm effect, the alarm device includes a motor 5 and an alarm body 7. The motor 5 is used to be fixedly installed on the power supply cabinet 100 and is communicatively connected with the control device 38; the alarm body 7 is arranged on the rotating shaft 6 of the motor 5, and the alarm body 7 is provided with a light-emitting component 8 and / or a display component 9.

[0070] The specific implementation form of the light emitting component 8 is not limited, and can be in the form of a light strip, a light emitting chip, etc., which is not limited here. The specific implementation form of the display component 9 is not limited, and can be a display screen, a projector, etc. Figures 1 to 3 As shown, in one embodiment, the light emitting assembly 8 includes a marquee, the display assembly 9 includes a display screen, the alarm body 7 is a multi-faceted prism, specifically a triangular prism, one side of the multi-faceted prism is equipped with an array of marquees, the side of the multi-faceted prism adjacent to the face where the marquee is located is equipped with an electronic screen, and another side of the multi-faceted prism is provided with a heat dissipation hole. When the cabinet door 2 is not locked, the control device 38 will input a high level to the motor 5 to start the motor 5, and the output end of the motor 5 drives the multi-faceted prism to rotate through the rotating shaft 6 and light up the marquee, which is convenient for maintenance personnel to respond quickly. At the same time, the safety prompt light 4 lights up, and the voice alarm component 10 alarms through a sound signal to increase the alertness of the maintenance personnel. The safety prompt light 4 is used to prompt that the cabinet door 2 is locked. On the one hand, the safety prompt light 4 and the voice alarm component 10 normally alarm after failure, and on the other hand, the visual prompt function of the safety prompt light 4 and the voice alarm component 10 can be expanded through the display screen to enrich the alarm prompt effect.

[0071] In one embodiment, the distance detection device includes a control device 38, the alarm device also includes a safety warning light 4 and a voice alarm component 10, the output end of the displacement sensor 33 is connected to a bridge rectifier circuit 39, the output end of the bridge rectifier circuit 39 is connected to a signal amplifier 40, the output end of the signal amplifier 40 is connected to the input end of the control device 38, the output end of the control device 38 is electrically connected to the safety warning light 4, the voice alarm component 10 and the motor 5, respectively, and a drive module 41 is connected between the motor 5 and the control device 38.

[0072] In the scheme of this embodiment, when the daily maintenance personnel complete the maintenance of the equipment, they close the cabinet door 2. When the key inserted into the lock cylinder 12 is rotated, the lock cylinder 12 can drive the connecting column 16, the locking hook 17 and the pressing member 19 to rotate synchronously. When the locking hook 17 rotates to match the engaging section 36 of the engaging fitting 35, the pressing member 19 presses the conduction button 37 at the same time, and the electrical connection between the displacement sensor 33 and the control device 38 is connected. The displacement sensor 33 works and emits a light signal or a sound wave signal directly in front of itself, the purpose of which is to send it to the location of the signal receiver 45. At the same time, at a preset time, The control device 38 receives the signal sent back by the signal receiver 45 and sends the signal to the signal amplifier 40 for amplification. The amplified signal is transmitted to the control device 38. The control device 38 compares the received return signal with the preset value. When the return signal is equal to the preset value within the error range, it indicates that the cabinet 1 and the cabinet door 2 are locked. At this time, the central processing unit transmits a high-level signal to the safety prompt light 4, lights up the safety prompt light 4, so that the maintenance personnel can quickly know the locking status of the cabinet door 2 and ensure that the door 2 is in a locked state. The cabinet 1 is closed and protected by the cabinet door 2, so as to realize the daily protection of the parts and lines in the cabinet 1.

[0073] To achieve the above objectives, the present application also proposes a power supply cabinet 100, comprising a cabinet body 1, a cabinet door 2 and a cabinet door locking detection device, wherein the cabinet door 2 is rotatably mounted on the cabinet body 1; the cabinet door locking detection device is the cabinet door locking detection device described above.

[0074] In the technical solution of the present application, by setting the distance detection device, when the cabinet door locking detection device is installed on the power supply cabinet 100, it is possible to detect the distance between the cabinet door 2 and the cabinet body 1 to determine whether the cabinet door 2 is locked, thereby avoiding the occurrence of the cabinet door 2 being unlocked. Since the cabinet door locking detection device adapted to the cabinet door 2 of the power supply cabinet 100 is set, the detection is convenient, fast and low-cost, which greatly improves the safety of the data center power supply cabinet 100, and improves the protection capability of the parts and lines inside the cabinet body 1 by preventing the cabinet door 2 from being missed, thereby ensuring the normal operation of the data center computer and greatly improving the maintenance efficiency of the data center power supply cabinet 100.

[0075] Further, it can be understood that the distance detection device can be arranged inside the cabinet 1 or on the outside of the cabinet 1, which is not limited here.
