[0001] This utility model relates to a protective storage device for rail transit, specifically a rail transit vehicle-mounted protective storage module with disaster recovery capabilities. Background Technology

[0002] Onboard protective storage modules for rail transit are a common type of data storage device in rail transit systems. Currently, most commercially available protective storage modules connect to external devices such as driving recorders via FPC cables. However, FPC cables are susceptible to impedance mismatch and electromagnetic interference during long-distance transmission, making them unsuitable for applications requiring both stable signal transmission and long-distance cabling.

[0003] In addition, the lifespan of the protection storage module is limited by the insertion and removal lifespan of the FPC cable, making it unsuitable for high insertion and removal frequency scenarios.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] Purpose of the utility model: The technical problem to be solved by this utility model is to provide a rail transit vehicle-mounted protective storage module that addresses the shortcomings of the existing technology. It is suitable for application scenarios that require both stable signal transmission and long-distance wiring, and also has a longer service life.

[0006] To address the aforementioned technical problems, this utility model discloses a rail transit vehicle-mounted protective storage module, which includes:

[0007] A protective housing, on which a waterproof connector for a wire harness is installed;

[0008] A memory, an adapter board, and a thermal protection structure are housed within the protective housing; the thermal protection structure at least encloses the memory and is used to secure the memory inside the protective housing.

[0009] And a wiring harness, wherein the adapter board is electrically connected to one end of the memory and the wiring harness, and the other end of the wiring harness extends out of the protective housing through the wiring harness waterproof connector.

[0010] Specifically, the protective housing includes a hollow housing body and a first end cap, one end of which is provided with a first opening; the first end cap is connected to the first opening by a first screw and a first sealing ring is provided between the first end cap and the first opening.

[0011] Specifically, the adapter plate is mounted to the side of the first end cover near the first opening by a second screw.

[0012] Specifically, the waterproof connector for the wire harness is installed on the side of the first end cap away from the first opening.

[0013] Specifically, the first end cap includes a planar sealing surface for connecting with the first opening and a boss formed in the middle of the planar sealing surface, and the first sealing ring is sleeved on the outer side of the boss.

[0014] Furthermore, the first end cover also includes an adapter plate limiting area, which is recessed in the center of the boss of the first end cover.

[0015] Specifically, the outer shell body and the first end cap are made of stainless steel, and the first sealing ring is a rubber sealing ring.

[0016] Furthermore, the first sealing ring is also provided with a second through hole through which the first screw passes.

[0017] Specifically, the thermal protection structure includes a heat-absorbing phase change layer and a heat-insulating layer. The heat-absorbing phase change layer encloses the memory, and the heat-insulating layer encloses the heat-absorbing phase change layer. The heat-absorbing phase change layer and the heat-insulating layer are spliced ​​structures.

[0018] The memory is connected to an FPC cable, which passes through the seam of the heat-absorbing phase change layer, the gap between the heat-absorbing phase change layer and the heat insulation layer, and the seam of the heat insulation layer to connect to the adapter board, so as to realize the electrical connection of the adapter board to the memory.

[0019] Specifically, the adapter board includes an adapter board base plate, a wire harness connection interface for connecting with the wire harness, an FPC cable connection interface for connecting with the FPC cable, and a conversion circuit.

Detailed Implementation

[0031] like Figures 1 to 5 As shown, this embodiment provides a rail transit vehicle-mounted protective storage module. The protective storage module includes: a protective housing 100, on which a wire harness waterproof connector 200 is mounted; a memory 310, an adapter plate 400, and a thermal protection structure 500 housed within the protective housing 100; the thermal protection structure 500 at least encloses the memory 310 and is used to fix the memory 310 inside the protective housing 100; and a wire harness 600, where the adapter plate 400 electrically connects the memory 310 to one end of the wire harness 600, and the other end of the wire harness 600 passes through the wire harness waterproof connector 200 and extends outside the protective housing 100. The wire harness 600 and the protective housing 100 are fixedly and sealed together via the wire harness waterproof connector 200.

[0032] In this invention, the memory 310 and the wiring harness 600 are electrically connected via an adapter board 400, enabling communication between the internal and external components of the rail transit vehicle-mounted protective storage module. Compared to related technologies that use FPC cables 320 to achieve communication between the internal and external components of the protective storage module, this invention uses the wiring harness 600 to meet the requirements of stable signal transmission in long-distance wiring applications.

[0033] In this utility model, the rail transit vehicle model can be a locomotive.

[0034] In one specific embodiment of the protective housing 100, the protective housing 100 includes a hollow housing body 110, a first end cap 120, a first sealing ring 130, and a first screw 170. One end of the housing body 110 is provided with a first opening 111. The first end cap 120 is connected to the first opening 111 by the first screw 170, and the first end cap 120 and the first opening 111 are provided with the first sealing ring 130.

[0035] In this embodiment, during assembly, the thermal protection structure 500 enclosing the memory 310 is placed into the housing body 110 through the first opening 111. Furthermore, in this embodiment, when the first end cap 120 is connected to the first opening 111 by the first screw 170, the first end cap 120 is sealed to the first opening 111 by the first sealing ring 130, thus achieving the sealing of the protective housing.

[0036] The first end cap 120 is connected to the first opening 111 by a first screw 170. For details, see [link to details]. Figure 4 The first end cap 120 has a first through hole 125 that matches the first screw 170. For aesthetic purposes, the first through hole 125 can also be a countersunk hole.

[0037] In another specific embodiment of the protective housing 100, such as Figure 2 and Figure 3 As shown, the protective storage module may also include a second end cap 140, a second sealing ring 150, and a third screw 160. The outer casing 110 also includes a second opening 112, which is located at opposite ends of the outer casing 110, along with the first opening 111. The second end cap 140 is fixedly connected to the second opening 112 by the third screw 160, and the second sealing ring 150 is disposed between the second end cap 140 and the second opening 112.

[0038] This embodiment makes it easier to place the thermal protection structure 500 containing the memory 310 into the outer casing 110 by setting the second opening 112 and the first opening 111, especially for modular thermal protection structures.

[0039] Furthermore, such as Figure 3 As shown, the first sealing ring 130 is also provided with a second through hole 131 for the first screw 170 to pass through.

[0040] In this embodiment, when assembling the outer shell body 110 and the first end cap 120, the first screw 170 is sequentially passed through the second through hole 131 of the outer shell body 110, the first sealing ring 130, and the first end cap 120 to form a hollow structure with good waterproof performance. At the same time, the first screw 170 also restricts the displacement of the first sealing ring 130.

[0041] It should be understood that for the protective housing 100 with the second end cap 140, the second sealing ring 150 can adopt the same structure as the first sealing ring 130, that is, it also has a through hole for the third screw 60 to pass through.

[0042] In a specific embodiment, such as Figure 5 As shown, the adapter plate 400 is mounted to the side of the first end cover 120 near the first opening 111 by the second screw 180. Specifically, as... Figure 4 As shown, the first end cap 120 has a screw hole 126 that matches the second screw 180.

[0043] A waterproof connector 200 for the wiring harness is installed on the protective housing 100. Specifically, as shown... Figure 1 and Figure 3 As shown, the wire harness waterproof connector 200 is installed on the side of the first end cap 120 away from the first opening 111.

[0044] Specifically, such as Figure 4 and Figure 5 As shown, the first end cap 120 includes a planar sealing surface 121 for connecting with the first opening 111 and a boss 122 formed in the middle of the planar sealing surface 121. The first sealing ring 130 is sleeved on the outside of the boss 122, and the boss 122 limits the first sealing ring 130.

[0045] The first sealing ring 130 is disposed between the flat sealing surface 121 of the first end cover 120 and the first opening 111 of the outer casing 110. Under the action of screw tightening, it plays a certain role in waterproofing and can better protect the memory in a water immersion environment.

[0046] Furthermore, such as Figure 4 As shown, the first end cover 120 also includes an adapter plate limiting area 123, which is recessed in the middle of the boss 122 of the first end cover 120. The adapter plate limiting area 123 is used to limit the adapter plate 400.

[0047] When the first end cap 120 is installed at the first opening 111 of the outer shell body 110, the internal thermal protection structure is tightly fitted with the boss 122 of the first end cap 120. By setting a recessed adapter plate limiting area 123 in the middle of the boss 122 of the first end cap 120, an installation space is provided for the adapter plate 400, and at the same time, the boss surface of the boss 122 is tightly fitted with the thermal protection structure to form a relatively limiting area.

[0048] Specifically, the outer casing 110 and the first end cap 120 are both made of stainless steel, which helps to improve the product's pressure resistance. The first sealing ring 130 is a rubber sealing ring.

[0049] Specifically, such as Figure 2 As shown, the thermal protection structure 500 includes a heat-absorbing phase change layer 510 and a heat insulation layer 520. The heat-absorbing phase change layer 510 encloses the memory 310, and the heat insulation layer 520 encloses the heat-absorbing phase change layer 510. The heat-absorbing phase change layer 510 and the heat insulation layer 520 are spliced ​​structures.

[0050] like Figure 2As shown, the memory 310 has an FPC cable 320 leading out. The FPC cable 320 passes through the seam of the heat-absorbing phase change layer 510, the gap between the heat-absorbing phase change layer 510 and the heat insulation layer 520, and the seam of the heat insulation layer 520 to connect with the adapter board 400, so as to realize the electrical connection of the adapter board 400 to the memory 310.

[0051] More specifically, such as Figure 5 As shown, the adapter board 400 includes an adapter board base plate 410, a wire harness connection interface 420 for connecting with the wire harness 600, an FPC cable connection interface 430 for connecting with the FPC cable 320, and a conversion circuit. The wire harness connection interface 420, the FPC cable connection interface 430, and the conversion circuit are all disposed on the adapter board base plate 410. The conversion circuit is electrically connected to the wire harness connection interface 420 and the FPC cable connection interface 430.

[0052] In one particular embodiment, such as Figure 1 As shown, the inner cavity of the outer shell 110 can be generally arranged in a cuboid shape. Correspondingly, the heat-absorbing phase change layer 510 and the heat insulation layer 520 are also hollow cuboid structures. For example, the heat insulation layer 520 is composed of six parts spliced ​​together: top, bottom, left, right, front, and back. The heat-absorbing phase change layer 510 is a phase change protective shell disclosed in Chinese Patent Publication No. CN222851124U, which provides a storage box with multiple reading methods.

[0053] It should be understood that the splicing structure of the heat-absorbing phase change layer 510 and the heat insulation layer 520 is not limited to the above-mentioned structure, and other existing structures can also be adopted.

[0054] Specifically, such as Figure 5 As shown, the wire harness 600 includes a wire harness body 610, a connector 620 for connecting with the wire harness connection interface 420, and a data interface 630. The connector 620 is connected to one end of the wire harness body 610, and the data interface 630 is connected to the other end of the wire harness body 610.

[0055] A sealed connection is achieved between the wiring harness 600 and the protective housing 100 via a waterproof connector 200. In one embodiment, the waterproof connector 200 can be a commercially available waterproof connector. Figure 1 and Figure 2As shown, the first end cap 120 has a connector body mounting hole 124. The wire harness waterproof connector 200 includes a connector body 210 and a locking nut 220. The connector body 210 is fixedly installed in the connector body mounting hole 124 by a first screw 170 and a fastening adhesive. The locking nut 220 is threaded onto the outer end of the connector body 210. The wire harness body 610 of the wire harness 600 passes through the connector body 210 and the locking nut 220 and leads out of the protective shell 100. When the locking nut 220 is tightened on the connector body 210, the wire harness waterproof connector 200 fixes and seals the wire harness 600 to the first end cap 120, thereby achieving a sealed connection between the wire harness 600 and the protective shell 100 through the wire harness waterproof connector 200.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
