Description

Technical Field

[0001] This utility model relates to the field of vehicle engineering technology, and in particular to an equipment compartment connector mounting structure and a vehicle. Background Technology

[0002] Currently, when assembling the connectors on the equipment compartment plate, the dynamic cable of the EMU uses an embedded installation method. Specifically, each connector is installed on a transition frame, and multiple connectors are mounted on a bracket. After cutting a notch in the equipment compartment plate, the bracket is embedded in the notch.

[0003] The main problems include: because transition frames and brackets are needed as intermediate connection structures to assemble the connectors on the equipment compartment, the intermediate connection structures also occupy a certain amount of space, which increases the difficulty of construction.

[0004] Therefore, how to simplify the connection between the equipment compartment and the connector is a technical problem that needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide an equipment compartment connector installation structure and vehicle, which can simplify the connection method between the equipment compartment and the connector.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A device compartment connector mounting structure includes: a device compartment having a mounting hole for mounting a single connector extending along a first direction; a connector being inserted into the corresponding mounting hole along the first direction, and the connector being sealed to the mounting hole.

[0008] For example, there is a gap between the mounting hole and the connector; the connector is also connected to a seal to seal the gap.

[0009] For example, it also includes an annular connecting plate, which is sleeved on the outside of the connector, fixed to the equipment compartment plate, and covers the gap.

[0010] For example, the seal includes a sealing ring and / or sealant.

[0011] For example, it also includes a flat connecting plate; the connecting plate is fixedly connected to the connecting plate along a direction perpendicular to the first direction, and is fixedly connected to one side of the equipment compartment plate along the first direction.

[0012] For example, the connecting plate is detachably fixed to the equipment compartment plate.

[0013] For example, multiple mounting holes and connectors are provided, and each mounting hole is connected to the connector in a one-to-one correspondence.

[0014] For example, the plurality of mounting holes are arranged in a matrix on the equipment compartment.

[0015] For example, the two equipment compartments are respectively connected to two opposite sides of the bogie and are arranged in a planar symmetrical manner; the equipment compartments gradually tilt from top to bottom in a direction away from the center line of the bogie.

[0016] A vehicle including the above-mentioned equipment compartment connector mounting structure.

[0017] The equipment compartment connector mounting structure provided by this utility model includes: an equipment compartment having a mounting hole for mounting a single connector through it along a first direction; and a connector that is inserted into the corresponding mounting hole along the first direction, and the connector and the mounting hole are sealed together.

[0018] In this type of equipment compartment connector mounting structure, mounting holes matching each connector are directly opened on the equipment compartment, allowing the connectors to be directly inserted into the equipment compartment. This simplifies the connection between the equipment compartment and the connectors, and the opening position of the mounting holes can be flexibly selected according to the actual location and number of connectors, reducing the need for intermediate connection structures and the opening area of ​​the equipment compartment, which helps to ensure the structural strength of the equipment compartment. Simultaneously, the sealed fit between the connector and the mounting hole prevents the equipment compartment from communicating with the external operating environment at the mounting hole, avoiding the influence of eddy currents during vehicle operation, reducing dust entry into the equipment compartment, and ensuring a completely sealed equipment compartment space. This isolates the cables inside the compartment from the harsh external operating environment, reducing the protection requirements for the connector socket tail and lowering maintenance and protection costs.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The core of this utility model is to provide an equipment compartment connector installation structure and vehicle, which can simplify the connection method between the equipment compartment and the connector.

[0034] This utility model provides a specific embodiment of the equipment compartment panel connector mounting structure, applied to rail vehicles. Please refer to... Figures 1 to 4 The equipment compartment connector mounting structure includes equipment compartment 3 and connector 1.

[0035] The equipment compartment 3 has a mounting hole 31 extending along the first direction X for installing a single connector 1. The connector 1 is inserted into the corresponding mounting hole 31 along the first direction X, and the connector 1 and the mounting hole 31 are sealed together. Specifically, the connection can be directly sealed or sealed through a sealing element. The effect of the sealing connection is to prevent the remaining space of the mounting hole 31 from connecting the inner and outer sides of the equipment compartment 3 after the connector 1 is installed.

[0036] In this type of equipment compartment connector installation structure, mounting holes 31 that match each connector 1 are directly opened on the equipment compartment 3, so that the connector 1 can be directly inserted into the equipment compartment 3. The opening position of the mounting hole 31 can be flexibly selected according to the actual position and number of connectors 1, reducing the need for intermediate connection structures and reducing the opening area of ​​the equipment compartment 3, which is conducive to ensuring the structural strength of the equipment compartment 3.

[0037] Meanwhile, the sealed fit between connector 1 and mounting hole 31 enables connector 1 to be installed on equipment compartment plate 3 while preventing the equipment compartment from communicating with the external operating environment at mounting hole 31. This avoids the influence of eddy currents during vehicle operation, reduces dust entering the equipment compartment, and ensures that the equipment compartment space is completely sealed, isolating the cables inside the compartment from the harsh operating environment outside the compartment. This also reduces the protection requirements for the tail of connector 1 socket and lowers maintenance and protection costs.

[0038] Furthermore, there is a gap between the mounting hole 31 and the connector 1. Optionally, the mounting hole 31 on the equipment compartment plate 3 for threading the cable of the connector 1 is a process hole with a diameter of 37 mm, slightly larger than the diameter of the metal cable connector at the tail of the connector 1. In this case, the gap ensures that the connector 1 can be smoothly inserted into the mounting hole 31. In addition, the connector 1 is also connected to a seal 5 to seal the gap and ensure a sealed fit between the connector 1 and the mounting hole 31. Of course, in other embodiments, the mounting hole 31 and the connector 1 can also be sealed by an interference fit.

[0039] Furthermore, to facilitate the assembly of connector 1, in some embodiments, the equipment compartment connector mounting structure further includes a flat connecting plate 2. For example... Figure 3 and Figure 4 As shown, the connecting plate 2 is fixedly connected to the connecting plate 3 along a direction perpendicular to the first direction X, and is also fixedly connected to one side of the equipment compartment plate 3 along the first direction X. In this case, the flat connecting plate 2 is selected as the connecting part between the equipment compartment plate 3 and the connector 1. The structure is simple and easy to process, and there is no need to process the connector 1 again due to connection requirements, which can avoid damage to the connector 1.

[0040] For example, connector 1 is not directly fixed to mounting hole 31, but directly fixed to connecting plate 2, and then fixedly connected to equipment compartment plate 3 through connecting plate 2. During assembly, connector 1 is first fixed to connecting plate 2 as one piece. After connector 1 is inserted into mounting hole 31, connecting plate 2 is then fixedly connected to a surface of equipment compartment plate 3 in the first direction X, specifically fixed to the outer surface of equipment compartment plate 3 in the first direction X.

[0041] For example, such as Figure 3 and Figure 4As shown, the connecting plate 2 is detachably fixed to the equipment compartment plate 3 to facilitate the maintenance of the connector 1. In other embodiments, welding or other methods can also be used. In some embodiments, the detachable connection can specifically be a bolt connection or a snap-fit ​​connection.

[0042] For example, the connecting plate 2 is a ring structure; optionally, as... Figure 4 As shown, the connecting plate 2 is a square ring plate, for example, a square plate with a side length of 50mm, and has through holes; or a circular ring plate can be used. During installation, the connecting plate 2 is sleeved on the outside of the connector 1 and fixed to the equipment compartment plate 3, covering the gap between the mounting hole 31 and the connector 1. Here, "covering" means that the parallel projection of the connecting plate 2 towards the equipment compartment plate 3 in the first direction X completely covers the gap between the mounting hole 31 and the connector 1. Furthermore, the connecting plate 2 is also fitted against the equipment compartment plate 3 in the first direction X to achieve a seal for the gap. In this case, the sealing element 5 includes the connecting plate 2. In addition, a sealing structure such as sealant can also be provided between the connecting plate 2 and the connector 1 to ensure a tight seal.

[0043] In some embodiments, the annular connecting plate 2 is bolted to the equipment compartment plate 3. Specifically, multiple bolts can be evenly arranged on the connecting plate 2 to connect the equipment compartment plate 3. In addition, the equipment compartment plate 3 has threaded holes around the mounting holes 31. When assembling the connecting plate 2, the bolts on the connecting plate 2 can be directly aligned with each threaded hole, and the connector 1 can be positioned on the equipment compartment plate 3 by means of bolting.

[0044] Of course, in other embodiments, the connecting plate 2 may not adopt a ring structure, but rather multiple connecting plates 2 may be arranged sequentially around the connector 1, specifically evenly, with each connecting plate 2 fixed to the equipment compartment plate 3. In this case, the total area occupied by the connecting plates 2 can be reduced, further improving the flexibility of the spacing setting between the connectors 1.

[0045] For example, the connecting plate 2 is a flat plate perpendicular to the first direction X. Alternatively, depending on the shape of the equipment compartment 3, the connecting plate 2 may be adapted, for example, to be an arc-shaped plate, to ensure a good fit with the equipment compartment 3 and improve the reliability of the connection.

[0046] For example, the connecting plate 2 can be fixedly connected to the connector 1 by means of interference fit, adhesive bonding or other methods. Specifically, sealant can be used for the adhesive bonding.

[0047] Furthermore, the sealing element 5 includes a sealing ring and / or sealant to ensure sealing performance. In some embodiments, after the connecting plate 2 is installed on the equipment compartment plate 3, sealant is applied between the connecting plate 2 and the equipment compartment plate 3 to seal the gap between the connector 1 and the mounting hole 31; alternatively, the connecting plate 2 may not be provided, and after the connector 1 is inserted into the mounting hole 31, sealant is applied directly in the gap between the two, and the cured sealant fixes the connector 1 to the mounting hole 31.

[0048] Furthermore, multiple mounting holes 31 and connectors 1 are provided, with each mounting hole 31 corresponding to a connector 1 to meet the application requirements of the connector 1. The mounting holes 31 can be flexibly arranged according to the positional requirements of the connector 1 in the vehicle width and height directions, such as... Figure 1 As shown, multiple mounting holes 31 can be arranged in a matrix on the equipment compartment plate 3.

[0049] Furthermore, such as Figure 2 As shown, the equipment compartment 3 is connected to the bogie 4, and the equipment compartment gradually slopes from top to bottom away from the bogie centerline S of the bogie 4. In addition, the two equipment compartments 3 are respectively connected to two opposite sides of the bogie 4 and are arranged in a planar symmetrical manner, specifically in a planar symmetrical manner with respect to the centerline of the bolster beam or the centerline of the bogie.

[0050] At this time, the equipment compartments 3 at both ends of the bogie 4 have the same tilt angle and spacing with the bogie centerline S, which can ensure that the initial tilt angle of the dynamic cable at the car body end is the same. In addition, by setting the position of the connector 1 in the width direction and height, the dynamic cables of the connector 1 at different positions can have the same spatial dynamic coupling relationship with respect to the bogie centerline S.

[0051] Furthermore, by integrating the connector 1 with the equipment compartment into a single, direct-insertion design, the different positions of connector 1 can be standardized into the same spatial relationship relative to the center position of bogie 4. Therefore, the dynamic envelope range and length calculation of the dynamic cable of bogie 4 can be completed with only one IPS software calculation and one on-vehicle small curve test, which greatly reduces the design cycle. This solves the problem of long verification cycle of the dynamic cable of connector 1 at four positions in traditional EMUs during the design phase. It can reduce the variety of dynamic cable lengths between connector 1 and bogie 4, improve the interchangeability of dynamic cables, shorten the design cycle, and make it difficult to distinguish cables with the same shape. After unifying the dynamic cable length of connector 1, the fault tolerance rate of replacement during the maintenance phase is improved, and the maintenance cost of connector 1 is reduced.

[0052] The equipment compartment connector installation structure provided by this utility model has the following beneficial effects: while realizing the installation of connector 1 on equipment compartment 3, it also realizes the complete sealing of the equipment compartment space, isolates the cables inside the compartment from the harsh operating environment outside the compartment, and makes the connector 1 installed in a sealed manner, reducing the protection requirements of the connector socket tail and reducing maintenance and protection costs; it integrates the installation of connector 1 at the car body end of the bogie dynamic cable with the equipment compartment sealing function, realizing the standardization of the spatial relationship of the dynamic cables of the four connectors.

[0053] In addition to the aforementioned equipment compartment panel connector mounting structure, this utility model also provides a vehicle, specifically a rail vehicle, and more specifically, a high-speed train. This vehicle includes an equipment compartment panel connector mounting structure, which can specifically be the equipment compartment panel connector mounting structure provided in any of the above embodiments.
