Description

Technical Field

[0001] The present invention relates to the technical field of rail transit systems, and in particular to a modular application management cabinet for a rail transit system. Background Art

[0002] Rail transit system refers to a type of transportation vehicle or transport system in which operating vehicles need to travel on specific tracks. With the development of railways, a large number of rail transit vehicles are in use at the same time across the country. To ensure that their routes are not affected, it is necessary to use a rail transit system modular application management cabinet to ensure the safety of vehicles during travel.

[0003] The existing rail transit system modular application management cabinet usually has a large number of application modules installed in the cabinet, such as track monitoring module, traffic information processing module and cooling module, etc. These modules need to be powered by a power supply mechanism when they are running. Generally speaking, multiple power supply batteries are installed in the power supply mechanism to power different modules to ensure the normal operation of the system, so the power supply mechanism needs to be running at all times and maintain a good working condition.

[0004] However, as the battery usage time increases, the heat generated by the battery will also increase. When the battery temperature is too high, it may cause the battery to fail, thus affecting the power supply efficiency. At this time, the staff needs to replace the faulty battery. But sometimes the staff is not next to the cabinet. When the battery in the cabinet sounds an alarm due to high temperature, the staff needs to rush to the scene first, then open the cabinet to take out the battery, and finally replace it. In this process, the staff takes a lot of time to come to the cabinet and replace the battery, which may cause information on the system to not be processed in time, thus affecting the safety of rail transit.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0036] See also Figure 1 - Fig.11 This embodiment proposes a rail transit system modular application management cabinet, including a body 1, wherein the body 1 is provided with a track monitoring module, a traffic information processing module, a cooling module and a power supply mechanism 2. Each module has a specific function, such as power management, signal transmission, data processing, environmental control, etc. The modular design also reduces the maintenance cost and time of the system, which is conducive to improving the overall operational efficiency.

[0037] In this embodiment, the power supply mechanism 2 includes a plurality of partitions 202 arranged in the transverse direction, the plurality of partitions 202 are evenly spaced, and a power supply interval is formed between two adjacent partitions 202, so that batteries can be installed on each partition 202 to ensure that the power supply of the power supply mechanism 2 is sufficient. Among them, a secondary battery cabinet 203 is provided on the partition 202 located at the bottom layer, and a main battery cabinet 204 is provided on the other partitions 202. The main battery cabinet 204 is provided with a working battery 205, and the secondary battery cabinet 203 is provided with a backup battery 206, so that the working battery 205 and the backup battery 206 do not interfere with each other under normal working conditions. In addition, the main battery cabinet 204 and the secondary battery cabinet 203 are both slidably connected to the corresponding partitions 202.

[0038] Furthermore, the power supply mechanism 2 also includes a vertically distributed wiring board 201, and a surface of the wiring board 201 facing the main battery cabinet 204 is provided with a plurality of circuit connectors 4 corresponding one to one with the working batteries 205. The left and right sides of the main battery cabinet 204 are provided with pop-up mechanisms 3. The pop-up mechanism 3 is used to disconnect the working battery 205 and the corresponding circuit connector 4 when the temperature of the working battery 205 exceeds a set threshold.

[0039] In order to make the disconnection process of the working battery 205 and the circuit connector 4 clearer, the ejection mechanism 3 is described in detail below:

[0040] The pop-up mechanism 3 includes a shell 301, a fixing rod 302 and a spring 303. The shell 301 is fixedly connected to the main battery cabinet 204, the fixing rod 302 is fixedly connected to the collection plate 201, the shell 301 is slidably mounted on the outside of the fixing rod 302, and an annular flange is also provided on the outside of the fixing rod 302. The two ends of the spring 303 respectively abut against the side wall of the annular flange and the inner wall of the shell 301, and the spring 303 is mounted on the fixing rod 302. In a natural state, the spring 303 is in a compressed state, and the spring 303 has a tendency to push the shell 301 to move outward, and the axial direction of the fixing rod 302 is consistent with the sliding direction of the main battery cabinet 204 and the auxiliary battery cabinet 203.

[0041] In addition, an elastic metal sheet 304 is fixed on the fixing rod 302, and there is a gap between the fixing rod 302 and the inner surface of the shell 301, so that the elastic metal sheet 304 can be tilted and bent between the shell 301 and the fixing rod 302. The shell 301 is provided with two limiting holes 305 for the elastic metal sheet 304 to be movably embedded, so that after the shell 301 pops out a certain distance, the elastic metal sheet 304 can enter the limiting holes 305 and be limited, so as to avoid the shell 301 popping out too long, causing the main battery cabinet 204 and the working battery 205 to collide with the inner wall of the body 1. A button 306 is fixed on the outer wall of the shell 301 and located at the position of the limiting hole 305 on the side away from the collection board 201. In the natural state, when the working battery 205 is connected to the circuit connector 4, the free end of the elastic metal sheet 304 is located in the limiting hole 305 on the side away from the collection board 201.

[0042] It is worth mentioning that the top of the elastic metal sheet 304 is in an inclined shape on the side facing away from the cable collection plate 201, and the side close to the cable collection plate 201 is in a vertical shape. Figure 5 As shown, the function is to facilitate embedding into the limiting hole 305 and clamping the shell 301. At the same time, after the user replaces the battery, it is convenient to push the working battery 205 toward the hub 201.

[0043] In order to enable the pressing process of the button 306 to be carried out as the temperature of the working battery 205 changes, the present application fixes a heat conducting plate 207 on one side of the main battery cabinet 204 close to the working battery 205, the heat conducting plate 207 is connected to the corresponding working battery 205, and one end of the heat conducting plate 207 extends above the button 306, and a deformation memory metal 208 is fixed on the side of the heat conducting plate 207 facing the button 306; when the temperature reaches the deformation temperature of the deformation memory metal 208, the deformation memory metal 208 stretches and squeezes the button 306 downward, so that when the working battery 205 fails and generates heat, the heat conducting plate 207 transfers heat to the deformation memory metal 208, thereby causing the deformation memory metal 208 to begin to deform, and then causing the deformation memory metal 208 to begin to squeeze the button 306.

[0044] Specifically, after the shape memory metal 208 squeezes the button 306, the button 306 will press the elastic metal sheet 304, causing the elastic metal sheet 304 to enter the shell 301, and then the spring 303 will pop out the shell 301 along the outside of the fixing rod 302, and the shell 301 will drive the main battery cabinet 204 and the working battery 205 to pop out, thereby disconnecting the working battery 205 and the corresponding circuit connector 4.

[0045] In some embodiments of the present application, an electrical metal plate 5 is fixedly provided on the wiring board 201, and a plurality of switching slots 501 corresponding to the circuit connectors 4 are provided on the electrical metal plate 5. Battery connectors 7 are fixedly provided on the working battery 205 and the backup battery 206. The circuit connector 4 passes through the switching slot 501 and is connected to the battery connector 7 on the working battery 205, so that the working battery 205 and the wiring board 201 are electrically connected, so that the working battery 205 can supply power to the wiring board 201, and the wiring board 201 can transmit the electric energy to each module. The battery connector 7 on the backup battery 206 is always connected to the electrical metal plate 5, and the circuit connector 4 passes through the switching slot 501. A switching mechanism 6 is provided in the switching slot 501, and the switching mechanism 6 is used to connect the backup battery 206 to the circuit connector 4, so that the battery connectors 7 on the working battery 205 and the backup battery 206 can be switched through the switching mechanism 6, so that when the working battery 205 is disconnected from the circuit connector 4, the backup battery 206 will be connected to the corresponding circuit connector 4.

[0046] Furthermore, an outer protective cover 701 is provided on the outer side of the battery connector 7, and the outer protective cover 701 is fixedly connected to the working battery 205. An inner protective cover 401 is provided on the outer side of the circuit connector 4, and the inner protective cover 401 is fixedly connected to the wiring board 201, so that the outer protective cover 701 and the inner protective cover 401 can protect the battery connector 7 and the circuit connector 4.

[0047] In order to make the switching process of the working battery 205 and the backup battery 206 more specific, the switching mechanism 6 is described in detail below:

[0048] The switching mechanism 6 includes a slider 601 slidably connected in the switching groove 501 along the vertical direction, a screw rod 602 is rotatably connected in the switching groove 501 along the sliding direction of the slider 601, the slider 601 and the screw rod 602 are threadedly connected, a gear 603 is mounted on the screw rod 602, a rack 604 is movably provided in the switching groove 501, and the length direction of the rack 604 is consistent with the moving direction of the main battery cabinet 204, the gear 603 and the rack 604 are meshed, and one end of the rack 604 is fixedly connected to the main battery cabinet 204, so that when the main battery cabinet 204 drives the working battery 205 to move outward, it will drive the rack 604 to move outward at the same time, and the rack 604 will drive the gear 603 to start rotating, thereby rotating the screw rod 602, and the rotation of the screw rod 602 will drive the slider 601 to start descending until it moves to the bottom of the switching groove 501.

[0049] In addition, a backup connector 605 is fixedly provided on the side of the slider 601 facing the circuit connector 4; when the slider 601 slides to the bottom of the slide groove, the backup connector 605 will be connected to the circuit connector 4. At this time, the battery connector 7 on the working battery 205 will be disconnected from the circuit connector 4, and the backup connector 605 will be connected to the circuit connector 4, thereby realizing the switching between the working battery 205 and the backup battery 206.

[0050] It is worth mentioning that the circuit connector 4 is a three-section structure consisting of a merging section 403, an arch section 404 and an insulating section 405, wherein the merging section 403 and the arch section 404 are both made of copper, and the insulating section 405 is made of hard plastic. In addition, there is only one merging section 403, and there are two arch sections 404 and two insulating sections 405 respectively. The two arch sections 404 are symmetrically distributed and integrally formed with the merging section 403. In a natural state, there is a gap between the two arch sections 404; the two insulating sections 405 are respectively connected to the ends of the two arch sections 404, and the two insulating sections 405 form a trumpet shape that is wide on the outside and narrow on the inside, which is used to facilitate the insertion of the battery connector 7.

[0051] Specifically, in the working state, the end of the battery connector 7 is located in the gap between the two arched sections 404, and the two arched sections 404 clamp the end of the battery connector 7. When the battery connector 7 is pulled outward and the spare connector 605 moves accordingly, when the end of the battery connector 7 moves to the inside of the two insulating sections 405, the bottom end of the spare connector 605 just extends between the two arched sections 404, so that the battery connector 7 opens the two arched sections 404, thereby facilitating the insertion of the spare connector 605. When the end of the spare connector 605 is inserted between the two arched sections 404, the two arched sections 404 also clamp the spare connector 605 to ensure that the circuit can be normally connected.

[0052] In order to enable the spare connector 605 to be plugged into the circuit connector 4 , the present application provides a through slot 402 on the side of the inner protective cover 401 facing the spare connector 605 to prevent the spare connector 605 from being blocked during the process of descending to the circuit connector 4 position.

[0053] It should be noted that the battery connector 7, the slider 601 and the spare connector 605 are all made of elastic metal, such as copper, and the screw rod 602, the gear 603 and the rack 604 are all made of insulating materials, such as plastic or ceramic.

[0054] The working principle and use process of the present invention are as follows: First, during the operation of the machine body 1, each working battery 205 is connected to the corresponding module in the machine body 1 through the circuit connector 4. If the working battery 205 in the power supply mechanism 2 fails, at this time, as the temperature of the working battery 205 continues to rise, the heat on the working battery 205 will be transferred to the deformation memory metal 208 through the heat conducting plate 207. When the temperature reaches the deformation temperature of the deformation memory metal 208, the deformation memory metal 208 will begin to stretch, and then the button 306 will be pressed down. The button 306 will be pressed down. 06 will press the elastic metal sheet 304 downward until the elastic metal sheet 304 breaks away from the limiting hole 305 and enters the shell 301; at this time, since the fixing rod 302 is in a fixed state, the spring 303 will pop the shell 301 outward along the axial direction of the fixing rod 302, and the shell 301 will drive the main battery cabinet 204 to move outward, and then drive the working battery 205 to move outward, so that the battery connector 7 and the circuit connector 4 on the working battery 205 are disconnected, thereby preventing the faulty working battery 205 from continuing to operate and preventing it from affecting the operating efficiency of the entire system.

[0055] When the main battery cabinet 204 moves outward, it will also drive the rack 604 on the back to move outward at the same time, and the rack 604 will drive the gear 603 to start rotating, and the gear 603 will drive the screw rod 602 to rotate, and the screw rod 602 will drive the slider 601 to move downward along the slide groove in the switching groove 501. When the working battery 205 and the circuit connector 4 are completely disconnected, the slider 601 will move to the bottom of the slide groove, and the spare connector 605 will pass through the through groove 402 and extend into the inner protective cover 401 and connect with the circuit connector 4, so that the spare battery 206 can transfer electrical energy to the slider 601 and the spare connector 605 through the electrical metal plate 5, and the spare connector 605 will transfer electrical energy to the hub 201 through the circuit connector 4, so that the spare battery 206 replaces the working battery 205 to start working until the staff comes to replace the faulty battery; this ensures the normal operation of the system and prevents the staff from replacing the battery for a long time, thereby providing protection for the operation of the device and the safety of rail transit.

[0056] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
