Description

Technical Field

[0001] This utility model relates to the field of data transfer technology, and in particular to a multi-interface expansion panel for a metering data transfer device. Background Technology

[0002] The application of targeted Internet of Things (IoT) technology in railway freight metering equipment is relatively mature. For example, railway companies in Germany, France, Canada, and the United States have widely applied IoT technology in areas such as loading quality and clearance measurement of freight trains. By installing various sensors and monitoring equipment on trains, they have achieved real-time monitoring and data transmission of cargo loading status, which has improved the accuracy of freight metering and the safety of transportation. In the process of data transmission, it is inevitable to use metering data relay equipment to transmit data to various monitoring devices and sensors.

[0003] In actual use, the interface size and number of interfaces of the relay equipment are limited. With the development of software and hardware, when it is necessary to add sensors or other data sources, it is difficult to match the number and type of interfaces in time. Therefore, multi-interface expansion panels are proposed. However, some existing expansion panels generally have fixed interfaces, resulting in low compatibility. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a multi-interface expansion panel for a metering data transfer device that can overcome or at least partially solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A multi-interface expansion panel for a metering data transfer device includes: a panel body, the panel body including a main module and at least one sub-module, the main module and the sub-module being detachably connected, and the sub-module being detachably connected to adjacent sub-modules; and further including: a connection interface disposed on one side of the main module; at least one first interface disposed on the other side of the main module; and at least one second interface disposed on one side of the sub-module.

[0007] In a preferred embodiment of the present invention, a limiting slot is provided on one side of both the main module and the sub-module, and a first contact unit is provided in the limiting slot. A card block corresponding to the limiting slot is provided on the side of the main module and the sub-module away from the limiting slot, and a second contact unit electrically connected to the first contact unit is provided on one side of the card block.

[0008] In a preferred embodiment of the present invention, a sealing groove is provided on one side of the limiting slot, and a sealing block that fits into the sealing groove is provided at the end of the card block.

[0009] In a preferred embodiment of this utility model, the second interfaces on the plurality of sub-modules are different.

[0010] In a preferred embodiment of this utility model, the connection interface is connected to the metering data transfer device via a connection cable.

[0011] In a preferred embodiment of this utility model, the main module near the first interface and the sub-module near the second interface are both rotatably connected to baffles, and magnetic strips are provided on the inner side of the baffles.

[0013] Compared with the prior art, this utility model provides a multi-interface expansion panel for a metering data transfer device, which has the following advantages:

[0014] 1.

In the process of mass production, the main module can use the same type, reducing mold opening costs and manufacturing costs.

[0016] 3. The multi-interface expansion panel of this metering data transfer equipment, by using connecting cables, can avoid obstructing other interfaces, and by increasing the length of the connecting cables, a suitable installation position can be selected for the entire panel body, avoiding the impact of train vibration.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example: Refer to Figures 1-6 A multi-interface expansion panel for a metering data transfer device includes: a panel body 1, the panel body 1 including a main module 2 and at least one sub-module 3, the main module 2 and the sub-module 3 being detachably connected and the sub-module 3 being detachably connected to adjacent sub-modules 3.

[0027] In a specific implementation, when it is necessary to expand the interface, in this embodiment, a USB cable is used to connect the main module 2 to the metering data transfer device. Then, according to the actual number and type of interfaces to be added, a sub-module 3 with a suitable second interface 301 is selected, and the sub-module 3 is spliced ​​with the main module 2 to achieve electrical connection. This enables the connection of multiple interfaces and has stronger applicability. On the one hand, it avoids the need to replace the metering data transfer device, and on the other hand, it has strong matching and adjustment capabilities.

[0028] In addition, in practical applications, it also includes: a connection interface 202, which is located on one side of the main module 2; at least one first interface 201, which is located on the other side of the main module 2; and at least one second interface 301, which is located on one side of the sub-module 3.

[0029] In this embodiment, the connection interface 202 can be a USB interface. The interface type of the connection interface 202 is the same as that of the first interface 201 to make up for the defect that the connection cable occupies one of the interfaces. In the process of mass production, the main module 2 can use the same type to reduce mold opening cost and manufacturing cost.

[0030] To enable the main module 2 to be spliced ​​with the sub-module 3 or the sub-module 3 with an adjacent sub-module 3, the following implementation method can be adopted: a limiting slot 4 is provided on one side of both the main module 2 and the sub-module 3, and a first contact unit 402 is provided in the limiting slot 4. A card block 5 corresponding to the limiting slot 4 is provided on the side of the main module 2 and the sub-module 3 away from the limiting slot 4. A second contact unit 502 electrically connected to the first contact unit 402 is provided on one side of the card block 5.

[0031] A sealing groove 401 is provided on one side of the limiting groove 4, and a sealing block 501 that fits into the sealing groove 401 is provided at the end of the locking block 5.

[0032] By using the interlocking method between the card block 5 and the limiting card slot 4, the first contact unit 402 and the second contact unit 502 are connected, so that the data of multiple modules can be transmitted to the metering data transfer device together.

[0033] The second interface 301 on multiple sub-modules 3 is different.

[0034] Different second interfaces 301 can be used to meet different connection expansion needs and can be adjusted appropriately.

[0035] The connection interface 202 is connected to the metering data transfer device via a connection cable.

[0036] Using a connecting cable avoids obstructing other interfaces and allows for the selection of a suitable installation location for the entire panel body 1 by increasing the length of the connecting cable, thus preventing train vibrations from affecting it.

[0037] Both the main module 2 near the first interface 201 and the sub-module 3 near the second interface 301 are rotatably connected to baffles 7, and magnetic strips 701 are provided on the inner side of the baffles 7.

[0038] The baffle 7 provides a certain degree of shielding for the first interface 201, preventing dust from entering when not in use, especially for the second interface 301 which has a reserved function.

[0039] The panel body 1 has a first dust cover 6 at one end and a second dust cover 601 at the other end.

[0040] The first dust cover 6 and the second dust cover 601 are used to shield and protect the first contact unit 402 and the second contact unit 502 at both ends, so as to facilitate the addition of the sub-module 3 later.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
