Description

Technical Field

[0001] This utility model relates to the field of rail transit technology, and in particular to an anti-detachment maintenance door for undercarriage cabinets. Background Technology

[0002] The electrical equipment of urban rail transit vehicles such as bullet trains and high-speed trains is partly installed on the train itself, distributed in electrical cabinets at both ends of each passenger compartment; and partly installed under the train. This latter equipment is generally installed in specially designed enclosed cabinets, which are then suspended under the train. The enclosed cabinets provide protection for the electrical equipment, preventing dust, rainwater, and other contaminants from damaging it. For ease of inspection and maintenance, access doors are installed on the cabinets. Smaller cabinets may have access doors on all four sides, while larger under-train cabinets also require access doors at the bottom to maintain equipment located in the center of the cabinet.

[0003] The maintenance door at the bottom of the cabinet should be airtight when closed to protect the components inside; it should also be anti-loosening to prevent it from loosening or falling due to vibration during train operation and causing damage. During maintenance, it should be easy to open and place for work in narrow spaces such as pits or train carriages. Currently, the maintenance door at the bottom of the undercarriage cabinets in existing trains is generally designed as a bottom cover plate, achieving a seal by tightening rubber strips with numerous bolts, and then using steel wire ropes to prevent loosening. This design results in a large workload during maintenance, difficult disassembly, and a high risk of thread stripping and failure.

[0004] In recent years, with the continuous growth of people's travel demands, in order to further improve the economic benefits of Fuxing bullet train transportation, China State Railway Group has put forward requirements for increasing the passenger capacity of bullet trains to various main engine manufacturers. Based on spatial analysis, compressing the space at the end of the passenger compartment and optimizing the space of the electrical distribution cabinet to increase seating is one aspect of achieving the increased passenger capacity. Therefore, it is necessary to move more onboard electrical cabinets to the undercarriage. Because there are many types and quantities of components in the electrical cabinets, the convenience of inspection and maintenance after moving them to the undercarriage is particularly critical. This places further demands on the design of the bottom inspection door of the undercarriage cabinets, making it necessary to optimize its structural design to make it more airtight, more resistant to detachment, and easier to maintain.

[0006] This utility model provides an anti-detachment maintenance door for a vehicle under-cabinet, installed at the bottom of the under-cabinet, comprising: A door frame, fixed to the bottom of the cabinet, has slots on both sides; and A door body is installed on the door frame. Sliding components are hinged to both sides of the door body near the slot. The sliding components are partially located within the slot. The sliding components are configured to move along the slot to allow the door body to slide and open or close the cabinet. The sliding components include elastic members that abut against the sliding components to restrict the sliding components within the slot. In one embodiment, the end of the slot is provided with a groove, which is recessed downward from the bottom of the slot, and when the door is opened, the sliding component is confined within the groove. In one embodiment, two sliding components are spaced apart on each side of the door, and a stop is provided in the middle of the slot. When the door is closed, one of the sliding components stops at the stop.

[0007] In one embodiment, the slot has a notch at the end of the stop block away from the groove. When the door is installed, the sliding component aligns with the notch and passes over the stop block into the slot.

[0008] In one embodiment, the sliding component includes: A connector, one end of which is hinged to the door body via a first pivot, and the other end of which is provided with a second pivot; A sliding member is disposed on the second rotating shaft, and the sliding member is located within the slot. The elastic element is sleeved on the first rotating shaft, with one end of the elastic element abutting against the connecting member and the other end abutting against the door body. Under the elastic force of the elastic element, the sliding member is restricted within the slot.

[0009] In one embodiment, the elastic element is a torsion spring, and under the torsion of the torsion spring, the connecting member tends to move toward the slot to confine the sliding member within the slot.

[0010] In one embodiment, the slider is a roller or a slider, and the surface of the roller or the slider moves along the slot.

[0011] In one embodiment, there are two door bodies with a sealing strip between them. Each door body has a locking element that locks the two door bodies and presses the sealing strip together.

[0013] In one embodiment, the door surface is provided with a recessed handle to facilitate pushing and pulling the door.

[0014] Compared with the prior art, the advantages of this utility model are that the elastic element abuts against the sliding component, restricting the sliding component within the slot, thereby restricting the door to the door frame. This ensures that after the access door is installed at the bottom of the cabinet, it cannot be detached by itself without external force. Even if the door lock is not tightened, the access door will remain in the slot and will not fall off. When maintenance is required, the door can be opened by pushing it to both sides of the cabinet. After the work is completed, the door can be pushed towards the center. The operation is convenient, and the sliding design of the door does not occupy the space at the bottom of the cabinet, making maintenance easy. Opening and closing the access door only requires pulling the lock key, without any other tools, making opening and closing the access door extremely convenient. Attached Figure Description

[0018] 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.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. Additionally, the technical solutions of the various embodiments can be combined with each other, but only on the basis of being achievable by those skilled in the art. When the combination of technical solutions is contradictory or impossible to implement, such a combination of technical solutions should be considered non-existent and not within the scope of protection claimed by this utility model.

[0021] The maintenance door at the bottom of the cabinet should be airtight when closed to protect the components inside; it should also be anti-loosening to prevent it from loosening or falling due to vibration during train operation and causing damage. During maintenance, it should be easy to open and place for work in narrow spaces such as pits or train carriages. Currently, the maintenance door at the bottom of the undercarriage cabinets in existing trains is generally designed as a bottom cover plate, achieving a seal by tightening rubber strips with numerous bolts, and then using steel wire ropes to prevent loosening. This design results in a large workload during maintenance, difficult disassembly, and a high risk of thread stripping and failure.

[0022] Furthermore, with the continuous growth of people's travel demands, in order to further improve the economic efficiency of Fuxing bullet train transportation, China State Railway Group has put forward requirements for increasing the passenger capacity of bullet trains to various main engine manufacturers. Based on spatial analysis, compressing the space at the end of the passenger compartment and optimizing the space of the electrical distribution cabinet to increase seating is one aspect of achieving the increased passenger capacity. Therefore, it is necessary to move more onboard electrical cabinets to the undercarriage. Because there are many types and quantities of components in the electrical cabinets, the convenience of inspection and maintenance after moving them to the undercarriage is particularly critical. This places further demands on the design of the bottom inspection door of the undercarriage cabinets, making it necessary to optimize its structural design to make it more airtight, more resistant to detachment, and easier to maintain.

[0023] like Figure 1 , Figure 2 and Figure 5 As shown, this utility model provides an anti-detachment maintenance door for a vehicle under-cabinet, installed at the bottom of the cabinet body 4. A door frame 1 is fixed around the bottom of the cabinet body 4, and slots 11 are provided on both sides of the door frame 1. A door body 2 is installed on the door frame 1, and sliding components are hinged to the two sides of the door body 2 near the slots 11. The sliding components are partially located in the slots 11 and are constructed to move along the slots 11, so that the door body 2 can be translated to open or close the cabinet body 4. The sliding components include elastic members 24, which abut against the sliding components to restrict the sliding components within the slots 11.

[0024] This utility model features an under-cabinet anti-detachment maintenance door. The elastic force of the elastic element 24 restricts the sliding component within the slot 11, thus securing the door 2 to the door frame 1. This ensures that once the maintenance door is installed at the bottom of the cabinet 4, it cannot detach without external force. Even if the door lock is not tightened, the maintenance door will remain within the slot 11 and will not fall off. When maintenance is required, the door 2 can be opened by pushing it to both sides of the cabinet 4. After completing the work, the door 2 can be pushed towards the center. The operation is convenient, and the sliding design of the door 2 does not occupy the bottom space of the cabinet 4, facilitating maintenance.

[0025] Example 1 like Figures 1 to 3 As shown, the anti-detachment maintenance door of the vehicle under cabinet of this utility model is installed at the bottom of the cabinet body 4 of the vehicle under cabinet. The bottom of the cabinet body 4 is fixed with a door frame 1, and the door body 2 is installed on the door frame 1.

[0026] like Figures 4 to 7 As shown, the door frame 1 has slots 11 on both sides, extending along the longer side of the door frame 1. Sliding components are hinged to the sides of the door body 2 near the slots 11. These sliding components are partially located within the slots 11 and can move along the slots 11 to allow the door body 2 to slide and open or close the cabinet 4. Each sliding component includes an elastic element 24, which abuts against the sliding component to confine it within the slots 11.

[0027] It should be noted that the access door needs to be opened frequently to inspect and maintain the internal components of cabinet 4. Therefore, the access door needs to be easy to open and close to reduce maintenance workload. In this embodiment, the door 2 is opened or closed by the sliding component moving within the slot 11. The door 2 is set to a sliding opening method, which is convenient to operate. Moreover, the sliding setting of the door 2 does not occupy the bottom space of cabinet 4, making it convenient for maintenance.

[0028] The door body 2 has a recessed handle 28 on its surface to facilitate pushing and pulling the door body 2.

[0029] The two ends of the slot 11 are closed, and the size of the door body 2 is designed to match the distance between the two slots 11, so that after the door body 2 is assembled into the slot 11, it can only move horizontally along the slot 11 and cannot be dislodged by vibration or bumps.

[0030] The end of the slot 11 is provided with a groove 12, which is recessed downward from the bottom surface of the slot 11. When the door 2 is opened, the sliding component moves from the slot 11 to both ends until the sliding component falls into the groove 12 and is confined within the groove 12. At this time, it can be confirmed that the maintenance door has reached the maximum opening and the next operation can be carried out. Since the groove 12 locks the sliding component, there is no need to worry about the maintenance door shaking back and forth and affecting the maintenance operation. The positioning by the groove 12 also prevents the maintenance door from sliding freely due to the tilt of the vehicle body, which would affect the maintenance operation under the vehicle.

[0031] In this embodiment, two sliding components are provided on each side of the door body 2 at intervals. A stop 13 is provided near the middle of the slot 11. When the door body 2 is closed, the sliding component near the joint side of the door body 2 is blocked by the stop 13, so that whether the maintenance door is open or closed, the sliding components on both sides are limited within the slot 11. Under the limitation of the end edge of the slot 11 and the middle stop 13, and under the elastic force of the elastic member 24, the maintenance door cannot come out on its own even when it is not locked. This fundamentally solves the problem of preventing it from coming out and avoids the situation where the maintenance door may become loose or fall onto the track and cause damage due to vibration during operation or negligence in locking.

[0032] Furthermore, the slot 11 has a notch 14 at the end of the stop 13 away from the groove 12. When the door 2 is installed, the sliding component aligns with the notch 14 and passes over the stop 13 to enter the slot 11.

[0033] like Figure 6 and Figure 7 As shown, the sliding assembly includes a connector 23 and a slider 26. One end of the connector 23 is hinged to the door body 2 via a first pivot 22. In this embodiment, a hinge seat 21 is fixed to the side edge of the door body 2, and one end of the first pivot 22 is hinged to the hinge seat 21. The other end of the connector 23 is provided with a second pivot 25, wherein the second pivot 25 is arranged parallel to the first pivot 22. The slider 26 is disposed on the second pivot 25 and is located in the slot 11. The elastic element 24 is sleeved on the first rotating shaft 22. One end of the elastic element 24 abuts against the connector 23, and the other end abuts against the hinge seat 21. Under the elastic force of the elastic element 24, the connector 23 tends to move toward the slot 11, which in turn causes the second rotating shaft 25 to tend to move toward the slot 11, thereby pressing the sliding element 26 into the slot 11. This ensures that after the access door is installed at the bottom of the cabinet 4, it cannot be detached by itself without external force. Even if the door lock is not tightened, the access door will remain between the two slots 11, so there is no need to worry about it falling off the track.

[0034] In this embodiment, the slider 26 is a roller, which is located in the slot 11 and can move along the slot 11.

[0035] like Figure 1 As shown, in one embodiment, two door bodies 2 are symmetrically arranged. Since working under the cabinet typically requires two people, the access door needs a sufficiently large opening to accommodate both workers, while maintaining a high level of sealing performance when closed. A single, large access door presents structural strength and rigidity design challenges, as conventional structures struggle to withstand the aerodynamic loads from under the vehicle. Therefore, in this embodiment, two door bodies 2 are symmetrically arranged, reducing the size of each door body 2 and thus improving the structural strength and rigidity of the access door.

[0036] like Figures 2 to 4 As shown, it should be noted that the two door bodies 2 must be easy to open for maintenance while ensuring a tight seal when closed. In this embodiment, a sealing strip 27 is provided between the two door bodies 2, and a locking member 3 is provided on the door body 2. The locking member 3 locks the two door bodies 2 and presses the sealing strip 27 to achieve a seal at the joint of the two door bodies 2.

[0037] In one embodiment, the locking element 3 includes a latch 31 and / or a latch lock 32. The latch 31 is located at the edges of the two door panels 2 facing each other. The latch 31 locks the two door panels 2 and presses the sealing strip 27. The latch 31 itself has a locking button and will not loosen on its own. Therefore, after the door panels 2 are locked by the latch 31, they are not easily opened without external force. When it is necessary to open the door panels 2, pressing the locking button of the latch 31 will unlock the latch 31.

[0038] Tensioner locks 32 are installed around the perimeter of the door 2 to lock the door 2 onto the cabinet 4. Multiple tensioner locks 32 are provided around each door 2. These locks compress the rubber strip within the sealing groove (not shown) of the cabinet 4, ensuring the airtightness of the access door. In this embodiment, the tensioner locks 32 can be opened by turning the four corner keys.

[0039] By tightening the latch 31 to tighten the two doors 2, the sealing strip 27 between the doors 2 is compressed, and the tightening lock 32 pulls upward to compress the rubber strip in the sealing groove on the cabinet 4, an IP55 waterproof rating can be achieved, which fully meets the airtightness requirements of the electrical cabinet under the vehicle.

[0040] This utility model's access door only requires tightening the four corner keys of the lock 32 to open and close, eliminating the need for other tools and making opening and closing the access door extremely convenient. During maintenance, open the lock 32, push the door 2 towards both sides of the cabinet 4, and when the sliding member 26 falls into the groove 12 at the end of the slot 11, it can be confirmed that the access door has reached its maximum opening, allowing for the next step of the operation. Since the groove 12 locks the sliding member 26, there is no need to worry about the access door swaying back and forth and affecting the maintenance work. After completing the work, push the door 2 towards the center, and when the sliding member 26 touches the stop block 13, it can be confirmed that it has slid into place, locking the latch 31 and operating the lock 32 to lock the access door. There is no need to manually adjust the positioning to confirm whether the edge of the access door is aligned with the center of the sealing groove.

[0041] Example 2 This embodiment has a basically the same structure as Embodiment 1, the only difference being the sliding member 26.

[0042] In this embodiment, the slider 26 is a slider, which is fixed to the end of the connector 23 or the second rotating shaft 25. The bottom surface of the slider is located in the slot 11. Sliding along the bottom surface of the slot 11 can also realize the opening and closing of the maintenance door.

[0043] Example 3 This embodiment has a structure that is basically the same as that of Embodiment 1, except that the number of door bodies 2 is different.

[0044] In this embodiment, when the access door opening at the bottom of the cabinet 4 does not need to be large, only one door 2 can be provided at the bottom of the cabinet 4. Sliding components and elastic elements 24 are provided on both sides of the door 2. Under the elastic force of the elastic elements 24, the sliding components are restricted within the slots 11 and can slide along the slots 11. When it is necessary to open the access door, it can be opened by sliding it to either side of the cabinet 4. In this embodiment, there is no need to provide a tensioning buckle 31 and a sealing strip 27.

[0045] Example 4 This embodiment has the same main structure as Embodiment 1, except that the connector 23 is different.

[0046] The function of connector 23 is to raise and lower the access door. In this embodiment, connector 23 can be replaced by a vertical slide and slider. This vertical slide and slider can move horizontally as a whole in the slot 11 at the bottom of the cabinet 4 (by rollers or slider). In this way, when opening the access door, first unlock the door lock, then pull the access door down along the vertical slide to disengage it from the sealing groove of the cabinet 4, and finally use the horizontal slot 11 to push the access door to the side of the cabinet 4 to complete the operation of opening the access door.

[0047] The assembly, closing, and opening process of the inspection door of this utility model is as follows.

[0048] During assembly, first lift one side of the door 2 horizontally to the bottom of the cabinet 4, aligning the set of rollers furthest from the fastening buckle 31 with the notch 14 in the middle of the slot 11. Press the connector 23 upwards, pushing the rollers over the stop 13 and into the slot 11. Because the elastic element 24 has elasticity, when the connector 23 is pushed, the rollers can move upwards with the connector 23, thus passing over the top of the stop 13. Then move the door 2 outwards and press the other set of rollers into the slot 11 using the same operation. This completes the installation of one side of the door 2. Assemble the other side of the door 2 using the same operation, thus completing the installation of the access door.

[0049] When closing, push the two assembled door bodies 2 towards the middle and move them in opposite directions. When the rollers hit the middle stop 13, the two door bodies 2 will come together. First, use the tensioning buckle 31 to pull the two door bodies 2 together, and then use the four corner keys to turn each tensioning lock 32 to the closed position in turn, thus completing the closing of the maintenance door.

[0050] To open, first press the locking button on the latch 31 to release it. Then, use the four-corner key to unlock each latch 32. Next, pull the door 2 down using the handle 28 on the door body 2, while simultaneously moving it to the side until the rollers fall into the grooves 12 at the end of the slots 11. This will open one side of the door body 2. The other side can be opened in the same way. Once the access door is fully open, the rollers will be confined within the grooves 12, preventing the access door from shaking and affecting operations.

[0051] This utility model relates to an under-cabinet maintenance door designed to prevent detachment. When the door 2 is opened and closed, the sliding member 26 slides within the slot 11, eliminating the need for removal. The only tool required is the key to tighten the lock 32, greatly improving the convenience of opening and closing the maintenance door. Furthermore, the elastic force (torsion) of the elastic member 24 keeps the sliding member 26 within the slot 11. Whether the door 2 is open or closed, the sliding members 26 on both sides are confined within the slot 11. With the limiting effect of the edge of the slot 11 and the middle stop 13, the maintenance door cannot detach itself even when unlocked, fundamentally solving the problem of detachment. The end of the slot 11 has a groove 12, which stops and positions the sliding member 26 when the door 2 is open, preventing the maintenance door from sliding freely due to vehicle tilt and affecting under-cabin maintenance operations. By tightening the latch 31 to tighten the left and right doors 2, compressing the sealing strip 27 between the doors 2, and by tightening the lock 32 to pull upward to compress the rubber strip in the sealing groove, an IP55 waterproof rating can be achieved, which fully meets the airtightness requirements of the electrical cabinet under the vehicle.

[0052] Although the present invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
