Description

Technical Field

[0001] The utility model relates to the technical field of coupler electrical connectors, in particular to a fully concealed communication electrical coupler. Background Art

[0002] In the field of rail transit technology, electric couplers are key components that connect electric locomotives or vehicles, and they undertake important functions such as traction, braking, and power transmission. With the advancement of technology and the increase in operational needs, higher requirements are placed on the communication capabilities of electric couplers. Especially in the application scenarios of rapid reconnection and flexible marshaling of vehicles, electric couplers need to be able to efficiently and stably transmit multiple communication signals to ensure smooth and safe train operation.

[0003] In order to meet the growing communication needs, the existing electric coupler design usually integrates a gigabit network communication module. The front end of the existing communication module mostly uses a circular PCB antenna. This antenna needs to be designed with a specific shell package when installed, and must be installed from front to back by drilling holes in the insulation panel of the electric coupler. Although this installation method can realize the communication function, it brings several significant technical problems.

[0004] First, this installation method has an adverse effect on the sealing performance of the electric coupler. Punching holes in the insulation panel of the electric coupler will destroy its original sealing structure, making it easy for water vapor and dust to enter the interior of the electric coupler. This not only affects the environment inside the electric coupler, but may also damage the internal electronic components, thereby affecting the transmission rate and stability of the signal.

[0005] Secondly, the need to punch holes in the electric coupler increases the manufacturing cost and complexity of the electric coupler. The punching process requires precise operation and control to ensure that the position and size of the hole meet the design requirements. This not only increases the manufacturing difficulty, but also increases the defective rate.

[0006] In addition, traditional communication modules have problems such as large space occupation and inconvenient installation in design. Since the circular PCB antenna requires additional shell packaging during the design and manufacturing process, it not only increases the cost, but also increases the size and weight of the module. In the space-constrained electrical coupler, it may also affect the layout and installation of other components. Moreover, the design and manufacturing of the shell packaging also increases the cost and maintenance difficulty. Summary of the invention

DETAILED DESCRIPTION

[0050] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments. 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.

Thus, a feature defined as "first", "second", and "third" may explicitly or implicitly include one or more of the features.

[0053] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0054] As attached Figure 1 -Attached Figure 7 As shown, in an illustrative embodiment of a fully concealed communication electric coupler of the utility model, it includes:

[0055] The electric coupler body includes a connecting panel 101, a shell 102 and a rear plate 103. The connecting panel 101 and the rear plate 103 are respectively mounted at two ends of the shell 102 to form a closed cavity with the shell 102;

[0056] A communication module, the communication module is arranged inside the closed cavity of the electric coupler body;

[0057] The power supply and signal conversion circuit module 3 is electrically connected to the communication module.

[0058] In the above embodiment, the communication module is integrated inside the electric coupler, and the communication module is installed on the coupling panel 101 from the inside. The surface of the coupling panel 101 on the coupling side does not reserve the holes required for the communication module except for the necessary electrical interfaces. When the two electric couplers are coupled, the communication parts 2 of the coupling panels 101 are connected, and the gigabit network signal on the vehicle reaches the power supply and signal conversion module 3, which converts the signal and sends it to the communication module. The communication module transmits the signal to the horn antenna of the opposite electric coupler through the horn antenna 2011, thereby realizing the gigabit network signal transmission between the two vehicles.

[0059] By placing the communication module inside the closed cavity of the electric coupler body, the communication module is fully hidden. This design not only improves the aesthetics of the electric coupler, but also enhances the protection performance of the communication module, avoids direct interference of the external environment on the communication module, and thus improves the stability and reliability of communication.

[0060] The communication module realizes communication between adjacent vehicles. The communication module of the vehicle on this side communicates with the electrical coupler on the opposite side to receive the network signal of the vehicle on the opposite side and / or the vehicle control signal, and transmits it to the vehicle system where it is located.

[0061] In some embodiments of the present invention, the communication module communicates wirelessly with the opposite electric coupler, including but not limited to millimeter wave communication and optical communication.

[0062] If the communication module uses millimeter waves for communication, for example, the millimeter wave transmission frequency band is 30GHz-300GHz, the wavelength is 1mm-10mm, and the network signal transmission is more stable.

[0063] Millimeter wave communication is adopted for communication. Millimeter wave communication has the characteristics of high frequency, high bandwidth, strong anti-interference ability and long transmission distance, and can provide faster data transmission rate and higher communication quality. It enables electric couplers in rail transportation systems such as high-speed trains to meet the growing demand for data transmission and improve the intelligence and automation level of train operation.

[0064] In some embodiments of the utility model, the communication module further includes a contact body 7, and the contact body 7 between the current side coupler and the opposite side coupler can be connected for communication. The contact body 7 described here can be a PCB antenna or other forms of plug-in communication components, similar to the limited communication method between couplers in the prior art. That is, in this embodiment, the electrical couplers can communicate with each other by contact wirelessly and by wire.

[0065] In some embodiments, two communication modules are provided, both of which are fixed on the connecting panel 101 through corresponding mounting plates. Preferably, the communication modules are symmetrically arranged on the connecting panel 101, namely communication module A and communication module B. Through such an arrangement, the electric coupler of this vehicle and the electric coupler on the opposite side can be designed to have exactly the same structure, and any two electric couplers can establish communication after being connected. After being connected, the communication module A of this vehicle communicates with the communication module B of the electric coupler on the opposite side through the network. At the same time, this design provides redundant configuration of the communication modules, enhances the fault tolerance of the system, and even if one of the communication modules fails, the other module can still work normally, ensuring the continuity and stability of communication. In addition, the dual-module design can also realize more complex communication functions, such as multi-path transmission of signals, further improving the reliability of communication.

[0066] Furthermore, the two communication modules can be functionally divided into a receiving module and a sending module. If the vehicle on this side has two communication modules, the vehicle on the opposite side also includes two communication modules accordingly. One of them is used as a receiving module, and the other is used as a sending module. The sending module of the vehicle on this side can be connected to the receiving module of the vehicle on the opposite side, and the receiving module of the vehicle on this side can be connected to the sending module of the vehicle on the opposite side. It should be noted that the function of the same communication module can be configured as needed. For example, at this moment, the communication module can be used as a receiving module, and at the next moment, the communication module can be used as a receiving module.

[0067] In some embodiments, the communication module includes: a horn antenna 2011 , a mounting plate 202 , and a communication board 201 .

[0068] The horn antenna 2011 and the mounting plate 202, the horn antenna 2011 is fixed to the rear surface of the connecting panel 101 through the mounting plate 202; its mounting position corresponds to the front surface of the connecting panel 101 as the communication part 2; the power supply and signal conversion module 3 is electrically connected to the horn antenna 2011 and to the vehicle body; the use of the horn antenna 2011, compared with the traditional circular PCB antenna, does not need to design a shell package, reduces the module's occupied area, and extends the service life of the communication module.

[0069] The communication board 201 is fixedly connected to the mounting plate 202, and the horn antenna 2011 is installed at one end of the communication board 201 close to the connecting panel 101; the communication distance after connecting is shortened, and the signal reception and output are enhanced;

[0070] The communication board 201 is also provided with a horn antenna circuit 2012 and a first connector 2013. The horn antenna circuit 2012 is electrically connected to the horn antenna 2011 and the first connector 2013. The first connector 2013 is electrically connected to the power supply and signal conversion circuit module 3. This design enables the various components of the communication module to be integrated more compactly, simplifies the electrical connection, and reduces the possibility of external interference. The first connector 2013 facilitates the electrical connection between the power supply and signal conversion circuit module 3 and the communication module, ensuring the efficiency and stability of signal transmission.

[0071] In some embodiments, the power supply and signal conversion circuit module 3 includes:

[0072] The second connector 301 is electrically connected to the first connector 2013;

[0073] The signal conversion circuit 302 is electrically connected to the second connector 301;

[0074] The third connector 303 is electrically connected to the signal conversion circuit 302 and the vehicle body. Exemplarily, the second connector 301 is an M12 connector, and the third connector 303 is a rectangular connector. The number of the second connector 301 and the third connector 303 can be set according to the number of horn antennas.

[0075] Through the signal conversion circuit 302, the electrical connection between the communication module and the vehicle body is realized, and at the same time, it adapts to the conversion requirements of different voltage levels and signal types, improves the compatibility and flexibility of the system, and the coordinated use of multiple connectors ensures a stable connection between the communication module and the vehicle body, ensuring the reliability of communication.

[0076] In some embodiments, the power and signal conversion circuit module 3 is mounted on the rear panel 103. Preferably, the power and signal conversion circuit module 3 is mounted on the rear panel 103 via a power and signal conversion circuit mounting plate 304, and the circuit and electrical module are protected by a power and signal conversion circuit housing 305.

[0077] Installing the power supply and signal conversion circuit module 3 on the rear plate 103 helps to centrally manage and maintain the power supply and signal conversion parts of the electric coupler, simplifies maintenance work, and reduces maintenance costs. At the same time, it also helps to protect these key components, avoid damage caused by external impact or environmental factors, and facilitate maintenance and upgrading.

[0078] In some embodiments, the coupling panel 101 is made of insulating material, which can effectively prevent the electric coupler from electrical short circuit and other faults during operation, ensure the electrical safety of the electric coupler during connection and disconnection, prevent accidental leakage of current, ensure the safety of vehicles and passengers, and also help improve the durability and reliability of the electric coupler and extend its service life.

[0085] The fourth connector 603 is electrically connected to the millimeter wave communication circuit 602 and the vehicle body. The fourth connector 603 is usually provided with two, namely, a network signal interface and a power interface. When the two electrical couplers are connected, the gigabit network signal on the vehicle reaches the network signal interface, the millimeter wave communication circuit 602 converts the signal, and transmits the signal to the millimeter wave communication module of the opposite electrical coupler through the antenna 601, thereby realizing the gigabit network signal transmission between the two vehicles.

[0086] In the above embodiment, the millimeter wave communication module is installed from the front end of the hanging panel 101.
