Description

Technical Field

[0001] This utility model belongs to the field of APM vehicle technology. Specifically, this utility model relates to a redundant connection structure for an APM vehicle electric hook. Background Technology

[0002] APM vehicles are increasingly being used on airport lines due to their convenient operation and low noise, as well as their small to medium capacity. Beijing Capital International Airport was the first in China to use the APM automated people mover system and has accumulated a wealth of experience over the past decade.

[0003] The APM (Automated People Mover) system primarily uses single-car trains with fully automated couplers. When passenger flow is high, multiple cars can be coupled together; when passenger flow is low, they can be decoupled and run as single cars again. Therefore, the fully automated couplers are crucial throughout the entire operation, requiring frequent coupling and decoupling.

[0004] Fully automatic couplers enable the complete automatic connection of two trains during coupling. Mechanical couplers establish a mechanical connection, while electric couplers automatically establish an electrical connection. After the automatic mechanical and electrical connections are completed, the two trains are coupled together and run as a single train, with all communication and signaling interoperability, effectively becoming a longer train formation. This allows for rapid expansion of transport capacity. Therefore, in locations like airports where passenger flow fluctuates periodically, trains frequently need to be coupled and decoupled, making the reliability of the couplers crucial.

[0005] The existing electrical connection between vehicles uses an electric coupler for automatic connection, with 78 pairs of pins on the coupler automatically engaging during the connection process. However, due to the large number of pins, after long-term use, individual pin failures are inevitable, causing problems with the electrical coupling signal of the entire train. This problem has occurred multiple times in actual operation, seriously disrupting the owner's normal coupling operation.

[0006] Therefore, for electric couplers used in a variety of scenarios, it is necessary to design a reliable system to ensure that all contacts can be reliably connected after the train is coupled.

[0007] Patent CN115144794A, published on October 4, 2022, discloses a device for inspecting pins and sockets for rail transit vehicles. This device includes a detection head carrier fixing housing, with a pin and socket detection body threadedly connected to one end of the housing. The pin and socket detection body includes a detection head connecting carrier, with a first external thread and a second external thread fixedly connected to the outer surfaces of both ends of the connecting carrier for threaded connection with the detection head carrier fixing housing. However, this device for inspecting pins and sockets for rail transit vehicles does not solve the aforementioned technical problems. Utility Model Content

[0008] The purpose of this invention is to address the shortcomings of existing technologies by providing a redundant connection structure for the electric hook of an APM vehicle that improves the reliability of electrical connections.

[0009] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0010] The redundant connection structure of the APM vehicle electric hook is provided, wherein the electric hook is connected between vehicles, and an electrical connection socket is also connected between the vehicles. The electrical connection socket includes a mounting plate, a male socket, and a female socket; the male socket is connected to the female socket, and the male socket and the female socket are respectively located on both sides of the mounting plate.

[0011] The female seat has an installation platform at its end, and the installation platform is connected to the installation plate by a first connecting bolt. The female seat includes an installation base, which is detachably connected to the end of the female seat. The installation plate has an opening, and the installation base is adapted to the opening. The end of the installation base has a first extension plate, and the end of the male seat has a second extension plate corresponding to the first extension plate. The first extension plate and the second extension plate are connected by a second connecting bolt. The inner side of the installation base is connected to the female seat by a third connecting bolt.

[0012] The mounting plate has an L-shaped structure, and there are two fixing holes on the top of the mounting plate. The fixing holes are waist holes.

[0013] There are two first extension plates, which are staggered at both ends of the mounting base.

[0014] Both the male and female connectors are connected to a plug hose, and both ends of the plug hose are connected to a connector.

[0015] Both the mounting base and the male seat are equipped with positioning pins and positioning sleeves, and the positioning pins and positioning sleeves are arranged in pairs.

[0016] The mounting base is provided with a sealing ring on its side.

[0017] The mounting plate is provided with reinforcing ribs on both sides.

[0018] The technical advantages of this utility model are as follows: The redundant connection structure of the APM vehicle electric coupler, achieved by adding electrical connectors between APM vehicles, creates a redundant connection structure. This ensures a completely reliable connection of the contacts after train coupling in various application scenarios, preventing the failure of the train's electrical coupling signal due to individual pin failures and guaranteeing the normal operation of APM vehicle coupling.

[0030] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0031] like Figure 1 and Figure 9As shown, the APM vehicle electric hook has a redundant connection structure. The electric hook is connected between vehicles, and an electrical connection socket is also connected between the vehicles. The electrical connection socket includes a mounting plate 1, a male socket 2, and a female socket 3. The male socket 2 is connected to the female socket 3, and the male socket 2 and the female socket 3 are located on both sides of the mounting plate 1.

[0032] Because APM vehicles are configured in groups, there is a need for coupling and decoupling. To ensure the reliability of the electrical connection between adjacent vehicles, even when the vehicles are already connected by mechanical coupler 7 and electric coupler 6, if... Figure 9 As shown, an independent redundant design is formed by adding electrical connection seats between adjacent APM vehicles. This design can be used with electric couplers, providing a redundant electrical connection between vehicles in addition to the automatic connection between electric couplers. After connection, each electrical signal has two paths to connect to another train. If one path fails, the other path can take over, without affecting the normal signal transmission of the train, thus greatly improving the reliability of train coupling. The female seat 3 has multiple core holes 33, and the male seat 2 has corresponding core pins 27. The male seat 2 and female seat 3 are electrically connected after mating. Both the male seat 2 and female seat 3 are equipped with corresponding grounding pins 25 and grounding holes 26 for protecting electrical equipment. The male seat 2 and female seat 3 are secured with mounting plates 1 and multiple bolts to form a stable connection.

[0033] like Figures 2 to 7As shown, the female seat 3 has a mounting platform 31 at its end, and the mounting platform 31 is connected to the mounting plate 1 by a first connecting bolt 32; the female seat 3 includes a mounting base 4, which is detachably connected to the end of the female seat 3; the mounting plate 1 has an opening 11, and the mounting base 4 is adapted to the opening 11; the end of the mounting base 4 has a first extension plate 41, and the end of the male seat 2 has a second extension plate 21 corresponding to the first extension plate 41; the first extension plate 41 and the second extension plate 21 are connected by a second connecting bolt 22; the inner side of the mounting base 4 is connected to the female seat 3 by a third connecting bolt 42. An opening 11 is designed on the mounting plate 1 to fit the mounting base 4. When the female base 3 is installed, the mounting base 4 can extend through the opening 11, facilitating connection with the male base 2 and providing a positioning effect for the bolt installation of the female base 3. Two first connecting bolts 32 and two second connecting bolts 22 are provided. The first connecting bolt 32, with its corresponding nut, ensures a stable connection between the mounting platform 31 and the mounting plate 1. The first connecting bolt 32 mounts the outer shell of the female base 3 onto the mounting plate 1. Four third connecting bolts 42 are provided to ensure a stable connection between the mounting base 4 and the outer shell of the female base 3. The second connecting bolts 22 on the other side of the mounting plate 1 stably connect the male base 2 to the mounting base 4, thus forming an effective connection between the mounting plate 1, the male base 2, and the female base 3, ensuring a stable fit between the male base 2 and the female base 3 and a firm connection to the vehicle body. The mounting platform 31 and the extension plate provide mounting positions for the bolts and also distribute the tightening force of the bolts. Furthermore, holes are provided on the other side of the mounting plate 1 at the opening 11 as temporary storage positions for the male base 2.

[0034] like Figure 8 As shown, the mounting plate 1 has an L-shaped structure. The top of the mounting plate 1 has two fixing holes 12, which are recessed holes. The L-shaped mounting plate 1 has a top surface and side surfaces, serving as the connection surface with the vehicle body and the connection surface with the connector, respectively. This design achieves a reduction in the number of parts. The top surface of the mounting plate 1 and the fixing holes 12 are used for connection with the vehicle body. The recessed holes 12 provide a certain adjustment margin, facilitating fine-tuning of the mounting point position of the mounting plate 1.

[0035] Two first extension plates 41 are provided, and the two first extension plates 41 are staggered at both ends of the mounting base 4. The above design makes the first connecting bolt 32 and the second connecting bolt 22 staggered on the upper and lower sides of the male base 2 and the female base 3, so that the force of the two connecting bolts is more uniform and the distance between the corresponding connection points is reduced, which helps to reduce the overall size of the connector.

[0036] like Figures 1 to 3As shown, both male connector 2 and female connector 3 are connected to a flexible plug 5, and both ends of the flexible plug 5 are connected to connectors 51. The flexible plug 5 effectively protects the internal electrical wiring harness. The flexible plug 5 connects to male connector 2, female connector 3, and the vehicle body wiring outlet through the connectors 51. The flexible plug 5 utilizes its own flexibility to withstand swaying, impact, and other stabilizing factors, ensuring reliable electrical connections. The connectors 51 of male connector 2 are connected to the bottom of the male connector 2 housing, ensuring that male connector 2 is not installed backwards.

[0037] like Figures 4 to 7 As shown, both the mounting base 4 and the male base 2 are equipped with positioning pins 23 and positioning sleeves 24, which are arranged in pairs. The mounting base 4 and the male base 2 each have two positioning pins 23 and two corresponding positioning sleeves 24, providing positioning guidance for the positioning and installation process of the male and female bases 3, and preventing damage to internal core pins 27, insert pins, and other structures due to inaccurate alignment or excessive contact force during installation.

[0038] like Figures 4 to 7 As shown, a sealing ring 43 is provided on the side of the mounting base 4. A corresponding receiving groove 28 for the sealing ring 43 is also provided at the opening 11 end of the male connector 2, thereby providing a reliable seal at the connection point of the connector.

[0039] like Figure 8 As shown, the mounting plate 1 has reinforcing ribs 13 on both sides. The reinforcing ribs 13 improve the structural strength of the mounting plate 1 and extend its service life.

[0040] This redundant electrical connector uses manual connection and can use standard connector 51, offering high reliability. Compared to the traditional method of solving the electric hook failure rate problem by optimizing the electric hook pins, this redundant electrical connector forms a redundant circuit for the electric hook connection, which is simple and effective, effectively solving the electric hook failure rate problem and possessing extremely high economic efficiency and practicality. After adopting the above-mentioned redundant electric hook design, the problem of unreliable signals between trains can be solved. After installation and use, it has been running on trains for nearly two years without any signal interruption problems, thus demonstrating its high practicality.

[0041] The redundant connection structure of the APM vehicle electric coupler, by adding electrical connectors between APM vehicles, forms a redundant connection structure for the vehicle electric coupler. This ensures a completely reliable connection of the contacts after train coupling in various usage scenarios, avoiding the problem of train electrical coupling signal failure due to individual pin failures of the electric coupler, and ensuring the normal operation of APM vehicle coupling. The electrical connector adopts the cooperation and installation of mounting plate 1, male connector 2 and female connector 3, which is simple and convenient to install and operate, and has high connection reliability. The structure of male connector 2 and female connector 3 is reasonably designed, the connection is firm, and it is highly practical.

[0042] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
