Electric hook device and railcar

[0001] Cross-reference of related applications

[0002] This application claims priority to Chinese Patent Application No. 202410673973.5, filed on May 28, 2024, entitled "Electric Hook Device and Rail Train", the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of rail train technology, and in particular to an electric hook device and a rail train. Background Technology

[0004] Currently, with the rapid development of urban rail transit, multiple-unit train technology is gradually being applied to urban subway rail transit. Multiple-unit operation of subway cars refers to the mechanical coupling of two identical trains into a single set, achieving synchronization of the two trains' control, signaling, and network system functions (electric coupling). When passenger flow is low, a single-unit operation mode is used; when passenger flow is high, a two-train multiple-unit operation mode can be adopted. Therefore, multiple-unit operation is a completely new operating mode that can meet passenger demand, reduce energy consumption, lower operating costs, and provide convenience for passengers' green travel.

[0005] Control signals, network signals, and power signals of coupled trains all need to be transmitted through electric couplers, and there are no jumper wires between the two trains. The amount of data transmitted is large. However, existing ordinary subway trains (6-car and 8-car sets) do not use electric couplers under normal operation, but only in the case of train rescue. Moreover, the data transmission capacity of electric couplers is limited and cannot meet the needs of coupled trains.

[0041] According to a first aspect of the embodiments of this application, an electric hook device is provided. The structure and working principle of the electric hook device will be described in detail below with reference to Figures 1 to 3.

[0042] According to the embodiments of this application, an electric coupler device is used for signal and network transmission between coupled trains. The electric coupler device includes an insulator assembly 100, which includes a network insulation component 110 and a control insulation component. In an embodiment, the network insulation component 110 includes a network insulation body 111, a plurality of 100 Mbps network modules 112, and a plurality of Gigabit network modules 113. The network insulation body 111 has a plurality of first receiving portions, each 100 Mbps network module 112 being disposed in a corresponding first receiving portion, and each Gigabit network module 113 being disposed in a corresponding first receiving portion.

[0043] In this embodiment, each 100 Mbps network module 112 has a first interface exposed on the outside of the network insulation body 111, and each Gigabit network module 113 has a second interface exposed on the outside of the network insulation body 111.

[0044] In an embodiment, the control insulation component includes a first control insulation body 121 and a second control insulation body 131, which are respectively connected to opposite sides of the network insulation component 110. The control insulation component includes a first set of contacts 122 disposed on the first control insulation body 121 and a second set of contacts 132 disposed on the second control insulation body 131.

[0045] Thus, the electric hook device provided according to the embodiments of this application can transmit Ethernet through the 100 Mbps network module 112 and transmit PIS (Passenger Information System) and video signals through the gigabit network module 113. The electric hook device also uses the first set of contacts 122 and the second set of contacts 132 to transmit control signals between the coupled trains. Therefore, after the electric hook devices of two trains are coupled, the electric hook device provided according to the embodiments of this application can realize the transmission of large amounts of data between the two trains, as well as the transmission of control signals, network signals, and power signals, thereby enabling train coupling.

[0046] The electric coupler device provided in the embodiments of this application is a large data transmission electric coupler device suitable for multiple-unit operation of rail vehicles. It meets the requirements of multiple-unit operation scenarios, overcomes the problems of single signal and insufficient transmission capacity of existing electric couplers, effectively integrates the relevant functions of vehicle control system, communication system and network system, expands the application scope of electric couplers, and has a simple structure and strong practicality.

[0047] In this embodiment, the network insulation member 110 and the control insulation member can present a generally block-shaped structure. Specifically, the network insulation body 111, the first control insulation body 121, and the second control insulation body 131 can all present a generally block-shaped structure.

[0048] In the embodiments, as an example, the 100 Mbps network module 112 for transmitting Ethernet can be, for example, a 4-core 100 Mbps network module 112, and the gigabit network module 113 for transmitting PIS and video signals can be, for example, an 8-core gigabit network module 113 (with a maximum signal transmission speed of gigahertz).

[0049] In this embodiment, the first receiving portion can be a hole into which both the 100Mbps network module 112 and the Gigabit network module 113 can be inserted. The first interface of each 100Mbps network module 112 is exposed on one side of the network insulating body 111, and the second interface of each Gigabit network module 113 is exposed on the same side as the side containing the first interface. In this embodiment, this side of the network insulating body 111 can be described as one side of the network insulating body 111 in a first horizontal direction. Correspondingly, the first control insulating body 121 and the second control insulating body 131 can be located on opposite sides of the network insulating body 111 in a second horizontal direction, wherein the first horizontal direction can be perpendicular to the second horizontal direction.

[0050] According to the electric hook device provided in the embodiments of this application, the network insulation body 111 may include a first base and a first limiting cover. The aforementioned plurality of 100Mbps network modules 112 and 100Mbps network modules 113 can be inserted into the first base, and the first limiting cover can be detachably connected to the first base to clamp the plurality of 100Mbps network modules 112 and 100Mbps network modules 113 together with the first base. In the embodiments, the first base and the first limiting cover together define a plurality of first receiving portions.

[0051] In this embodiment, the first base can be a block structure, on which holes corresponding one-to-one with the aforementioned plurality of 100Mbps network modules 112 and the aforementioned plurality of gigabit network modules 113 are formed; the first limiting cover can be a plate structure, on which holes corresponding one-to-one with the aforementioned plurality of 100Mbps network modules 112 and the aforementioned plurality of gigabit network modules 113 are formed. In other words, the holes on the first limiting cover also correspond one-to-one with the holes on the first base. Therefore, the holes on the first limiting cover and the corresponding holes on the first base together form a first receiving portion.

[0052] In this embodiment, taking the 100Mbps network module 112 as an example, the 100Mbps network module 112 can generally be presented as a stepped shaft shape. The end of the 100Mbps network module 112 near the first interface, that is, the front end, can have a stepped shoulder. When the 100Mbps network module 112 passes through the corresponding hole on the first limiting cover plate, the side of the first limiting cover plate facing the first base can abut against the shoulder of the 100Mbps network module 112, thereby preventing the 100Mbps network module 112 from being further exposed to the outside of the first limiting cover plate (that is, the side facing away from the first base member) through the corresponding hole on the first limiting cover plate.

[0053] Subsequently, in this embodiment, the first limiting cover plate and the first base can be connected by fastening components to fix the 100 Mbps network module 112. Here, the fastening component can be, for example, a screw. In this embodiment, the first base can have multiple internal threaded holes, and the first limiting cover plate can also have multiple corresponding internal threaded holes. The corresponding screws are simultaneously screwed into two internal threaded holes located on the first base and the first limiting cover plate, respectively, thereby connecting the first limiting cover plate and the first base (or bolts and nuts can be used as fastening components, and through holes can be provided on the first limiting cover plate and the first base for the bolts to pass through).

[0054] Similarly, the installation method for gigabit network module 113 is the same, and you can refer to the above description of the installation method for 100 Mbps network module 112, which will not be repeated here.

[0055] In this embodiment, both the 100Mbps network module 112 and the gigabit network module 113 can be segmented network modules for easy replacement. Specifically, taking the 100Mbps network module 112 as an example, it can be divided into a front-end area and a back-end area. The back-end area is plugged into the first base, while the front-end area has the aforementioned first interface. Both the front-end and back-end areas are detachable. Therefore, when the 100Mbps network module 112 is used frequently, for example, after tens of thousands of connections, if the front-end area shows severe wear, it can be removed from the back-end area, and a new front-end area can be installed. This avoids the situation where replacing the 100Mbps network module 112 requires detaching it from the cable.

[0056] Similarly, the segmentation of the gigabit network module 113 can be the same as that of the 100 Mbps network module 112, and the replacement process can be referred to the above description, which will not be repeated here.

[0057] According to the electric hook device provided in the embodiments of this application, both the first control insulation body 121 and the second control insulation body 131 may include a second base and a second limiting cover. The first set of contacts 122 can be inserted into the second base of the first control insulation body 121, and the second set of contacts can be inserted into the second base of the second control insulation body 131. The second limiting cover of the first control insulation body 121 and the second base of the first control insulation body 121 can jointly clamp the first set of contacts 122, and the second limiting cover of the second control insulation body 131 and the second base of the second control insulation body can jointly clamp the second set of contacts 132.

[0058] In this embodiment, the fixing method of the first set of contacts 122 and the second set of contacts 132 can be the same as the fixing method of the 100 Mbps network module 112 and the Gigabit network module 113 described above. This fixing method facilitates the installation and replacement of the 100 Mbps network module 112, the Gigabit network module 113, the first set of contacts 122, and the second set of contacts 132. That is to say, the second base and the second limiting cover are similar in form to the first base and the first limiting cover, respectively, and will not be described again here.

[0059] According to the electric hook device provided in the embodiments of this application, the first group of contact components may include a plurality of first contact components, each of which may include a first rear plug and a first front plug that are detachably connected to each other, the first rear plug being inserted into the first control insulation body 121. Similarly, the second group of contacts includes a plurality of second contact components, each of which includes a second rear plug and a second front plug that are detachably connected to each other, the second rear plug being inserted into the second control insulation body 131.

[0060] Thus, the electric hook device provided according to the embodiments of this application is similar to the network module with front and rear segments mentioned above. The first contact and the second release can also be formed as components that can be separated front and rear. Thus, when replacing the first contact and the second contact, only the first front plug and the second front plug need to be replaced, without having to remove the contact from the corresponding cable, thereby improving the replacement efficiency.

[0061] As an example, in the embodiment, the first contact and the second contact can both be control pins. Specifically, the same type of elastic contact as IC142 can be used, and the size of its mounting hole and the amount of compression during connection are consistent with IC142. The 100 Mbps network module 112 and the Gigabit network module 113 can use YUTAKA EC005 Gigabit and EC006 100 Mbps network modules 112.

[0062] According to the electric hook device provided in the embodiments of this application, the side of the first control insulation body 121 facing the network insulation body 111 may have a first stepped positioning surface, and the side of the network insulation body 111 facing the first control insulation body may have a second stepped positioning surface, the first stepped positioning surface and the second stepped positioning surface being fitted together. Similarly, the side of the second control insulation body 131 facing the network insulation body 111 may have a third stepped positioning surface, and the side of the network insulation body 111 facing the second control insulation body 131 may have a fourth stepped positioning surface, the third stepped positioning surface and the fourth stepped positioning surface being fitted together.

[0063] Thus, in the electric hook device provided according to the embodiments of this application, the first control insulation body 121 and the network insulation body 111, as well as the second control insulation body 131 and the network insulation body 111, are all positioned by interlocking with each other using a stepped positioning structure. This reduces the difficulty of installing the first control insulation body 121, the network insulation body 111, and the second control insulation body 131 together, reduces the time consumed in positioning the three, and improves installation efficiency.

[0064] In this embodiment, the first control insulation body 121, the network insulation body 111, and the second control insulation body 131 are arranged separately to facilitate the installation of corresponding electrical components on each (mainly network modules for the network insulation body 111 and contact elements for the control insulation body). Since the corresponding electrical components also need to be connected to cables, if the first control insulation body 121, the network insulation body 111, and the second control insulation body 131 were initially configured as an integral structure, during the sequential installation of electrical components, some electrical components would inevitably be connected to cables first. The first connected cable may cause the position of the integral insulation component to twist, making it difficult to install subsequent cables, or the first connected cable may create the risk of tangling for the cables connected later.

[0065] However, if the first control insulation body 121, the network insulation body 111, and the second control insulation body 131 are set up separately, they can be assembled after the connection of their respective electrical components and cables is completed. This makes it easier to determine the position of the cables, the corresponding insulation bodies, and the electrical components as a whole, and the risks mentioned above are less likely to occur.

[0066] In this embodiment, the cooperation between the first control insulation body 121 and the network insulation body 111 can be the same as the cooperation between the second control insulation body 131 and the network insulation body 111. Here, we will only use the cooperation between the first control insulation body 121 and the network insulation body 111 as an example for explanation.

[0067] In this embodiment, the first stepped positioning surface of the first control insulating body 121 is convex on the side near the first control insulating body away from the first set of contacts 122, while the corresponding position of the network insulating body 111 is recessed. Conversely, the first stepped positioning surface of the first control insulating body 121 is recessed on the side near the first control insulating body where the first set of contacts 122 are located, while the corresponding position of the network insulating body 111 is convex. Similarly, the second control insulating body 131 and the network insulating body 111 are coupled in the same way, and their specific functions will be explained in the following description.

[0068] According to the electric hook device provided in the embodiments of this application, the electric hook device may further include a housing 400, and an insulator assembly 100 may be disposed within the housing 400. In the embodiments, the insulator assembly 100 may further include a first support member 200 and a second support member 300. The first support member 200 may include a first pressing part, and the second support member 300 may include a second pressing part.

[0069] In this embodiment, the first support member 200 can be detachably connected to the housing 400, so that the first pressing part and the housing 400 can jointly clamp the first control insulation body 121, and the second support member 300 can be detachably connected to the housing 400, so that the second pressing part and the housing 400 can jointly clamp the second control insulation body 131.

[0070] In the embodiments, the first support member 200 and the second support member 300 are installed in the same way and work in the same way. Here, only the first support member 200 is used as an example for illustration.

[0071] In this embodiment, unlike the control insulation body and network insulation body 111 described above which are formed of insulating material, the first support member 200 and the second support member 300 may both be formed of metallic material.

[0072] In this embodiment, the first support member 200 and the first control insulation body 121 can still cooperate with each other in a stepped manner. Specifically, the first support member 200 and the second control insulation body 131 each form a stepped surface, and then the two stepped surfaces are fitted together to realize the positioning of the first support member 200 on the second control insulation body 131.

[0073] In one embodiment, as an example, the stepped surface of the first support member 200 is convex on the side near the first control insulation body 121 where the first set of contacts 122 are disposed; correspondingly, the stepped surface of the first control insulation body 121 facing the first support member 200 is recessed at the corresponding position. Similarly, the stepped surface of the first support member 200 is recessed on the side away from the first control insulation body 121 where the first set of contacts 122 are disposed; correspondingly, the stepped surface of the first control insulation body 121 facing the first support member 200 is convex at the corresponding position.

[0074] Therefore, when the first control insulating body 121 contacts the housing 400 on the side away from where the first set of contacts 122 are located, the first control insulating body 121 is pressed against the housing 400 on both sides in the second horizontal direction by the network insulating body 111 and the first support member 200, respectively. Similarly, the second control insulating body 131 is pressed against the housing 400 on both sides in the second horizontal direction by the network insulating body 111 and the support member, respectively. As an example, both the first support member 200 and the second support member 300 can have through holes and be detachably connected to the housing 400 by screws.

[0075] According to the electric hook device provided in the embodiments of this application, the housing 400 may include a housing body 410 and a cover member 420 movably connected to the housing body 410. The cover member 420 may be configured to be movable relative to the housing 400 to expose and cover the insulator assembly 100.

[0076] Thus, the electric hook device provided according to the embodiments of this application can protect the insulator assembly 100 when the cover is movably provided, and allow the insulator assembly 100 to connect with the external electrical structure when the insulator assembly 100 is exposed.

[0077] In an embodiment, the cover member 420 can seal the insulator assembly 100, i.e., when the insulator assembly 100 is sealed, the cover member 420 and the shell body 410 form a sealed space. In an embodiment, the shell body 410 may have two openings in a first horizontal direction, with the cover member 420 pivotally connected to the outside of one of the openings. As an example, the electric hook device may also include a tension spring, one end of which is connected to the cover member 420 and the other end to the outside of the shell body 410, so that when the cover member 420 is opened, the tension spring is stretched, thereby providing a restoring force to the cover member 420. A sealing strip may be provided between the cover member 420 and the shell body 410 to seal the opening when the cover member 420 seals the insulator assembly 100.

[0078] A cable can be led out through an opening on the other side of the housing body 410. The cable can be placed inside a corrugated pipe 500, and a heavy-duty plug 600 can be provided at the end of the corrugated pipe 500. In this embodiment, the housing 400 can adopt an existing housing structure, the structure of which will not be described in detail.

[0079] According to the electric hook device provided in the embodiments of this application, the network insulation body 111 may have a symmetrical plane, and the aforementioned plurality of 100Mbps network modules 112 are symmetrically arranged about the symmetrical plane. The first interface of the 100Mbps network module 112 on one side of the symmetrical plane is a male interface, and the first interface of the 100Mbps network module 112 on the other side of the symmetrical plane is a female interface. Similarly, the network insulation body 111 has a symmetrical plane, and the plurality of gigabit network modules 113 are symmetrically arranged about the symmetrical plane. The second interface of the gigabit network module 113 on one side of the symmetrical plane is a male interface, and the second interface of the gigabit network module 113 on the other side of the symmetrical plane is a female interface.
