[0049] The core of the present invention is to provide a safety control device and a chassis, which avoids the accidental opening of the chassis and ensures the safety of the chassis through the control method of software coordinating with hardware.

[0050] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0051] Please refer to Figure 1 , Figure 1 A schematic structural diagram of a safety control device provided by the present invention.

[0052] The safety control device comprises a housing 2 and a cover 1 which can be opened relative to the housing 2. The housing 2 is provided with a slide groove 4, the first end of which extends to the edge of the housing 2. The cover 1 is provided with a clamping column 3, which extends into the slide groove 4 through the first end of the slide groove 4 and is slidably connected with the slide groove 4. The housing 2 is also provided with two fixing components 5 which are connected with the slide groove 4. The two fixing components 5 are respectively located at two sides of the slide groove 4 and have a preset distance from the second end of the slide groove 4.

[0053] Each fixing component 5 includes a retractable first magnetic attraction component;

[0054] The first end of the first magnetic attraction component is fixed to the end of the fixing component 5 away from the slide slot 4, and is connected to the electric control module 6;

[0055] The electric control module 6 is used to control the second end of each first magnetic component to extend into the slide slot 4 and be attracted and connected when receiving the first identification signal indicating that the opening is prohibited, so as to limit the card column 3 between the second end of the slide slot 4 and the second end of the first magnetic component.

[0056] In this embodiment, considering that in order to avoid the accidental opening of the server chassis in the prior art, the methods adopted are mainly: the first method is to add a lock with a matching key to the chassis, but once the matching key is lost, it is difficult to open it again, which is not appropriate; the second method is to add screws to the chassis cover to achieve locking, but only one screwdriver is needed to open the model, so it still cannot effectively prevent the chassis from being opened by humans by mistake. In order to solve the above technical problems, this application provides a safety control device, which reliably avoids the accidental opening of the chassis through hardware settings combined with software control logic.

[0057] Specifically, the safety control device can be applied to the chassis. Please first refer to Figure 1 , Figure 1 The schematic diagram of the design structure of the housing 2, the cover 1, the slide 4 and the clamping column 3 of the safety control device is shown. The slide 4 and the clamping column 3 are arranged in a matching manner. The specific number of sets can be set according to actual needs, such as Figure 1 As shown, there are two sets (i.e., two slide slots 4 and correspondingly arranged clamping columns 3). The specific shape of the slide slot 4 includes but is not limited to being arranged as follows Figure 1 The slide groove 4 is shown in an L-shaped structure; the clamping column 3 can penetrate from the first end of the slide groove 4, and when the cover body 1 is not opened relative to the shell body 2, the clamping column 3 penetrates from the first end of the slide groove 4 and finally stops at the second end of the slide groove 4; during the opening process of the cover body 1 relative to the shell body 2, the clamping column 3 starts to slide from the second end of the slide groove 4 and passes through the first end of the slide groove 4 to realize the opening of the cover body 1 relative to the shell body 2.

[0058] Therefore, please refer to Figure 2 , Figure 2 As an example diagram, the principle of limiting the sliding of the clamping column 3 in the present application is explained from the perspective of the inside of the housing 2. Figure 2 Due to the limited space of the illustration, the electric control module 6 is shown in the form of a circle plus a reference mark. It should be noted that the fixing component 5 can be specifically fixed on the side of the housing 2 (the side is Figure 1 The side where the slide slot 4 is shown is not particularly limited in this application as to how to fix it. Preferably, each of the fixing components 5 itself can be made of insulating material, such as non-conductive plastic material, so as not to affect the subsequent electric control pull-in logic.

[0059] Each fixing member 5 includes a retractable first magnetic attraction component corresponding to Figure 2 It can be seen that the fixing component 5 located at the upper part of the slide slot 4 includes a retractable first magnetic attraction component 51, and the fixing component 5 located at the lower part of the slide slot 4 includes a retractable first magnetic attraction component 52, and Figure 2 For the sake of convenience of explanation, the first end of one of the first magnetic components 51 is fixed to the end of the corresponding fixed component 5 away from the slide slot 4 (the end is indicated by a bold black line here), and the first end of the other first magnetic component 52 is fixed to the end of the corresponding fixed component 5 away from the slide slot 4 (the end is also indicated by a bold black line here), and the first magnetic component 51 and the first magnetic component 52 are both connected to the electric control module 6. Therefore, taking the first magnetic component 51 as an example, the specific application includes but is not limited to opening a hole on the fixed component 5 including the first magnetic component 51, for passing the connecting wire between the first magnetic component 51 and the electric control module 6.

[0060] It should also be noted that the preset distance between the two fixing parts 5 and the second end of the slide slot 4 can be based on actual needs, but it should meet the sliding restriction logic of the card column 3. Therefore, when the electric control module 6 receives the first identification signal indicating that opening is prohibited, it can control the second end of each first magnetic component to extend into the slide slot 4 and be attracted to connect, so as to limit the card column 3 between the second end of the slide slot 4 and the second end of the first magnetic component; it can be understood that when the electric control module 6 does not receive the first identification signal, or when it receives the second identification signal indicating that opening is allowed, it can control the second ends of each first magnetic component to repel each other, that is, Figure 2 As shown, Figure 2 It is shown that the card column 3 is at the second end of the slide slot 4, and the second ends of the first magnetic attraction component 51 and the second magnetic attraction component 52 repel each other, so that the first magnetic attraction component 51 is still in the fixed component 5 at the upper part of the slide slot 4, and the second magnetic attraction component 52 is still in the fixed component 5 at the lower part of the slide slot 4, so that the card column 3 can still slide from the second end of the slide slot 4 to the first end of the slide slot 4, thereby realizing the opening of the cover body 1 relative to the shell body 2.

[0061] In summary, the present application provides a safety control device, which avoids accidental opening of the chassis and ensures the safety of the chassis through the above-mentioned software and hardware control method.

[0062] Based on the above embodiments:

[0063] As a preferred embodiment, the first magnetic attraction component 51 in one of the fixing components 5 includes:

[0064] A first telescopic component 511, one end of which is connected to the end of the fixing component 5 away from the slide groove 4, and the other end of which is connected to the first end of the first metal rod;

[0065] A first metal rod, on which a first coil is wound, and two ends of the first coil are respectively connected to the electric control module 6 .

[0066] In this embodiment, a first magnetic attraction component 51 of a fixing component 5 includes a first telescopic component 511, a first metal rod, and a first coil wound on the first metal rod. The specific connection structure can be found in the above description and will not be described here. Figure 2 , Figure 2 It is assumed that the fixing component 5 located at the upper part of the slide groove 4 is one of the fixing components 5 described in this embodiment (of course, the fixing component 5 at the lower part of the slide groove 4 can also be one of the fixing components 5 described in this embodiment, and the above setting is made here only for the convenience of the figure mark display). In addition, Figure 2 Due to the limited space of the picture display, only the first structure 512 composed of the first metal rod and the wound first coil is shown in the form of a rectangular frame. As for the setting of the connecting wire between it and the electric control module 6, in the actual application design, it can be connected with the connection structure described above. Specifically, a hole can be opened on the fixing component 5 to pass through the connecting wires between the two ends of the first coil and the electric control module 6. No special limitation is made here. In addition, the first telescopic component 511 includes but is not limited to a spring.

[0067] As a preferred embodiment, the first magnetic attraction component 52 in another fixing component 5 includes:

[0068] A second telescopic member 522, one end of which is connected to the end of the fixing member 5 away from the slide slot 4, and the other end of which is connected to the first end of the second metal rod;

[0069] A second metal rod, on which a second coil and a third coil are respectively wound, and both ends of the second coil and both ends of the third coil are respectively connected to the electric control module 6.

[0070] In this embodiment, the first magnetic attraction component 52 in another fixing component 5 may include a second telescopic component 522 and a second metal rod on which a second coil and a third coil are wound. Therefore, the specific connection structure can be referred to above and will not be described here. Figure 2 , Figure 2 It is assumed that the fixing component 5 located at the bottom of the slide slot 4 is another fixing component 5 described in this embodiment (of course, the fixing component 5 at the top of the slide slot 4 can also be another fixing component 5 described in this embodiment. The above setting is made only for the convenience of the figure mark display, and it is a fixing component 5 different from the above one of the fixing components 5). In addition, Figure 2 Due to the limited space of the picture display, only the second structure 521 composed of the second metal rod and the wound second coil and third coil is shown in the form of a rectangular frame. As for the setting of the connecting wire between it and the electric control module 6, in the actual application design, it can be connected with the connection structure described above. Specifically, a hole can be opened on the fixing component 5 to pass through the connecting wires between the two ends of the second coil and the two ends of the third coil and the electric control module 6, which is not particularly limited here. In addition, the second telescopic component 522 includes but is not limited to a spring.

[0071] As a preferred embodiment, the electric control module 6 includes:

[0072] A first processor 61, a first output end of which is respectively connected to a first end of the first coil, a first end of the second coil, and a first end of the third coil;

[0073] The first switch module 62 has a control end connected to the second output end of the first processor 61, a first end connected to the second end of the first coil and the third output end of the first processor 61, a second end connected to the second end of the second coil, and a third end connected to the second end of the third coil; wherein the level signals output by the first output end of the first processor 61 are opposite to those output by the third output end;

[0074] The first processor 61 is used to control the conduction between the first end and the third end of the first switch module 62 when receiving a first identification signal indicating that opening is prohibited, so that the second ends of the first metal rod and the second metal rod are attracted and connected; when receiving a second identification signal indicating that opening is allowed, the first processor 61 controls the conduction between the first end and the second end of the first switch module 62, so that the second ends of the first metal rod and the second metal rod repel each other.

[0075] In this embodiment, on the basis of the second coil and the third coil being wound on the second metal rod at the same time, the electric control module 6 may include a first processor 61 and a first switch module 62. It should be noted that the BMC (Baseboard Management Controller) chip is usually used for receiving information and management, and the first processor 61 here includes but is not limited to a single-chip microcomputer, the input end of which may be connected to the BMC, and the BMC sends the first identification signal and the second identification signal to the single-chip microcomputer, and the single-chip microcomputer controls the execution of corresponding processing actions.

[0076] For details, please refer to Figure 3 , Figure 3 The schematic diagram of the structure of an electric control module 6 provided by the present invention. (For the convenience of explanation, the first end, the second end and the third end of the first switch module 62 are briefly labeled with characters 1, 2 and 3 respectively, and the same applies to the first coil, the second coil and the third coil.) It can be understood that the first output end of the first processor 61 can always output a low level, and the third output end of the first processor 61 can always output a high level. It can be seen that for the first coil on the first metal rod in the first structure, there is always a current in the first direction (assuming that when there is a current in the first direction, it is equivalent to the N pole). Therefore, the first processor 61 can control the conduction port of the first switch module 62 through its own second output end, and then control the magnetic state of the second metal rod. First of all, it should be noted that in the actual setting, the first coil on the first metal rod is connected to the first coil 61. The second end of the second coil and the first end of the third coil are located on one side of the second metal rod, and the second end of the third coil and the first end of the second coil are both located on the other side of the second metal rod, so as to ensure that when the first processor 61 controls the first end and the second end of the first switch module 62 to be turned on, the second coil on the second metal rod flows with current in the first direction (therefore, based on the above assumption, the second metal rod is equivalent to the N pole and repel each other with the first metal rod); when the first processor 61 controls the first end and the third end of the first switch module 62 to be turned on, the third coil on the second metal rod flows with current in a second direction opposite to the first direction (therefore, based on the above assumption, the second metal rod is equivalent to the S pole and attracts each other with the first metal rod).

[0077] In addition, the first switch module 62 includes but is not limited to a controllable switch device that is essentially based on the principle of a single-pole double-throw switch, and can also be implemented by using two controllable switches, which is not specifically limited here.

[0078] As a preferred embodiment, the first magnetic attraction component 52 in another fixing component 5 includes:

[0079] A third telescopic member, one end of which is connected to the end of the fixed member 5 away from the slide slot 4, and the other end of which is connected to the first end of the third metal rod;

[0080] A third metal rod, on which a fourth coil is wound, and two ends of the fourth coil are respectively connected to the electric control module 6 .

[0081] In this embodiment, it is provided that the first magnetic attraction component 52 in another fixed component 5 may include a third telescopic component and a third metal rod on which a fourth coil is wound. Therefore, please refer to the above description for the specific connection structure, which will not be repeated here. It should be noted that as for the setting of the connecting wire between the fourth coil and the electric control module 6, the actual application design can refer to the description of the above connection structure. Specifically, a hole can be opened on the fixed component 5 to pass through the connecting wires between the two ends of the second coil and the two ends of the third coil and the electric control module 6. No special limitation is made here. In addition, the third telescopic component includes but is not limited to a spring.

[0082] As a preferred embodiment, the electric control module 6 includes:

[0083] A second processor 63;

[0084] A second switch module 64, a control end of which is connected to the first output end of the second processor 63, and a third end of which is connected to the first end of the fourth coil;

[0085] The third switch module 65 has a control end connected to the second output end of the second processor 63, a first end connected to the first end of the second switch module 64, the third output end of the second processor 63 and the first end of the first coil, a second end connected to the second end of the second switch module 64, the fourth output end of the second processor 63 and the second end of the first coil, and a third end connected to the second end of the fourth coil; wherein the level signals output by the third output end and the fourth output end of the second processor 63 are opposite;

[0086] The second processor 63 is used to control the conduction between the first end and the third end of the second switch module 64 and the conduction between the second end and the third end of the third switch module 65 when receiving the first identification signal indicating that the opening is prohibited, so that the second ends of the first metal rod and the third metal rod are attracted and connected; when receiving the second identification signal indicating that the opening is allowed, the second end and the third end of the second switch module 64 are controlled to be connected and the first end and the third end of the third switch module 65 are controlled to be connected, so that the second ends of the first metal rod and the third metal rod repel each other.

[0087] In this embodiment, on the basis that only the fourth coil is wound on the third metal rod, the electric control module 6 may include a second processor 63, a second switch module 64 and a third switch module 65. It should be noted that the BMC chip is usually used for receiving information and management, and the second processor 63 here includes but is not limited to a single-chip microcomputer, the input end of which may be connected to the BMC, and the BMC sends the first identification signal and the second identification signal to the single-chip microcomputer, and the single-chip microcomputer controls the execution of corresponding processing actions.

[0088] For details, please refer to Figure 4 , Figure 4 Schematic diagram of another electric control module provided by the present invention. (For ease of explanation, the first end, the second end and the third end of the second switch module 64 are briefly labeled with characters 1, 2 and 3, respectively, the third output end and the fourth output end of the second processor 63 are briefly labeled with characters 3 and 4, respectively, and the first coil, the fourth coil and the third switch module 65 are also briefly labeled.) It should be noted that, considering that there are too many circuits involved in the figure and the appendix Figure 4 The connection between the control end of the second switch module 64 and the third switch module 65 and the second processor 63 is shown in the form of a circle plus a reference mark. It can be understood that the third output end of the second processor 63 always outputs a high level, and the fourth output end of the second processor 63 always outputs a low level. It can be seen that the first metal rod always passes through the current in the third direction (assuming that when the current in the third direction passes through, it is equivalent to the N pole).

[0089] Therefore, when the second processor 63 receives the first identification signal, the current flow direction of the control implemented in the above embodiment is: the third output end of the second processor 63-the second end of the third switch module 65-the third end of the third switch module 65, the second end of the fourth coil, the first end of the fourth coil, the third end of the second switch module 64, the first end of the second switch module 64-the fourth output end of the second processor 63. It can be seen that for the fourth coil at this time, the current flowing therethrough is the current in the fourth direction opposite to the third direction (therefore, the third metal rod is equivalent to the S pole and is mutually opposite to the first metal rod).
