Referring to fig. 2 to 14, the structure and implementation process of the rail vehicle and its car provided in this embodiment will be described below with reference to the accompanying drawings. It is to be understood that, in some examples, a part of the structure of the vehicle cabin is hidden in order to embody the structure of the electrical cabinet or the inspection door.

Referring to fig. 2 to 6, the car 1 provided in this embodiment includes: electrical cabinet 11, inspection door 13, and seal 15.

For convenience of description, in this embodiment, the side of the electrical cabinet 11 facing the inspection door 13 is not taken as the front (as indicated by an arrow Y in the drawing), and the side of the electrical cabinet 11 facing away from the inspection door 13 is taken as the back; taking one end of the electrical cabinet 11 facing the floor of the carriage 1 as a lower end, and taking one end of the electrical cabinet 11 facing away from the floor of the carriage 1 as an upper end (as shown by an arrow Z in the figure); the other two sides are the left side and the right side respectively (as shown by arrow X in the figure).

The electrical cabinet 11 has a cabinet body 111, and the cabinet body 111 can be a box structure, so as to facilitate the electrical cabinet 11 to have certain sealing performance, and facilitate the realization of functions such as dust prevention and water prevention. The cabinet 111 encloses a mounting space, that is, the space in the cabinet 111 forms a mounting space, and some components and system devices are arranged in the mounting space. A plurality of mounting plates can be arranged in the mounting space, the mounting plates can be connected with the cabinet body 111, and at least part of the components and the system equipment can be mounted on the mounting plates. In this embodiment, the arrangement and installation of the components and the system devices in the installation space are not specifically limited, and those skilled in the art can set the components and the system devices according to actual needs.

In addition, the vehicle body 1 in the present embodiment may be a head car having a cab, or may be a passenger car body 1 for accommodating passengers or cargo; correspondingly, the electrical cabinet 11 in this embodiment may be an electrical cabinet 11 in a head car, and may also be an electrical cabinet 11 in a passenger car compartment 1.

One side of the cabinet 111 may be connected to a side wall 19 of the car 1, for example, the cabinet 111 may be connected to the side wall 19 through a connection corner brace, so as to ensure positioning reliability and stability of the electrical cabinet 11. At this time, a certain gap is formed between the cabinet 111 and the side wall 19, and the gap is matched with the size of the connecting corner brace. An inner partition wall 17 is further provided in the vehicle compartment 1, and the inner partition wall 17 may be located on a front side of the electrical cabinet 11 to block a gap between the electrical cabinet 11 and the side wall 19. The built-in partition wall 17 can also be connected with the side wall 19 through a connection corner brace, and the connection corner brace can also be positioned at the gap between the side wall 19 and the electrical cabinet 11. In addition, the rear side of the cabinet 111 and the side of the cabinet 111 facing the corridor may be respectively provided with a rear partition wall and a side partition wall, and the rear partition wall and the side partition wall may be specifically the same as or similar to those in the prior art. Compared with the related art, in the present embodiment, the gap between the cabinet 111 and the side wall 19, the gap between the cabinet 111 and the rear partition wall, and the gap between the cabinet 111 and the side partition wall do not need to be increased.

An inspection window 112 is arranged at the front side of the cabinet 111, and an inspection door 13 is arranged at the inspection window 112. The inspection door 13 is openably and closably provided at the inspection window 112. Thus, when the electrical cabinet 11 needs to be overhauled or maintained, the inspection door 13 can be opened so that an operator can overhaul and maintain components, system equipment and the like in the electrical cabinet 11 from the inspection window 112. After the maintenance and repair operation is completed, the inspection door 13 may be closed so that the inspection door 13 covers the inspection window 112, so as to shield the components and the system equipment in the cabinet 111.

One side of the inspection door 13 is connected to an internal partition wall 17 located on the front side of the electrical cabinet 11; the inspection door 13 is also connected to the cabinet 111 when it is in the closed state. Wherein the inspection door 13 has an open state and a closed state; when the inspection door 13 is in an open state, the components and system equipment in the electrical cabinet 11 can be exposed from the inspection window 112, so that an operator can overhaul and maintain the components or system equipment in the electrical cabinet 11 from the inspection window 112; when the inspection door 13 is in a closed state, the inspection door 13 is covered on the inspection window 112 to seal the installation space, and the inspection door 13 also has a decoration effect, so that the integrity of the interior trim part of the vehicle is improved, and the attractiveness of the interior of the vehicle is improved.

In some examples, the inspection door 13 may be detachably coupled to the interior partition wall 17 at the front side by screws, and the inspection door 13 may also be detachably coupled to the cabinet 111 by screws. So, when needing to overhaul and maintain components and parts or system equipment in the regulator cubicle 11, can unscrew the screw, take off inspection door 13, the operation personnel can overhaul and maintain components and parts or system equipment in the regulator cubicle 11 from the operation window department. After the completion of the inspection and maintenance work, the inspection door 13 is mounted to the interior partition 17 plate and the cabinet 111 by screws.

In other examples, one side of inspection door 13 may be pivotally connected to interior bulkhead 17 by a hinge, and inspection door 13 may be disposed to extend in a vertical direction relative to the axis of rotation of interior bulkhead 17. The inspection door 13 can also be connected with the cabinet 111 through screws; thus, when the components or system equipment in the electrical cabinet 11 need to be overhauled and maintained, the screws can be unscrewed to drive the inspection door 13 to rotate in the direction away from the installation space so as to open the inspection window 112, and an operator can overhaul and maintain the components or the system equipment in the electrical cabinet 11 from the inspection window 112; after the maintenance and repair work is completed, the inspection door 13 is mounted to the cabinet 111 by screws.

Alternatively, the inspection door 13 may be connected to the cabinet 111 through a locking mechanism 132, and the locking mechanism 132 may be a locking structure commonly used in rail vehicles; thus, when the components or system equipment in the electrical cabinet 11 need to be overhauled and maintained, the locking mechanism 132 can be opened through a key to enable the locking mechanism 132 to be in an unlocked state, then the inspection door 13 is driven to rotate in the direction away from the installation space to open the inspection window 112, and an operator can overhaul and maintain the components or system equipment in the electrical cabinet 11 from the inspection window 112; after the maintenance and repair work is completed, the locking mechanism 132 is switched to the locked state, so that the inspection door 13 is connected to the cabinet 111 through the locking mechanism 132.

In this embodiment, when the inspection door 13 is in a closed state, the inspection door 13 may be connected to the interior partition wall 17 and may also be connected to the cabinet 111, thereby implementing installation and fixation of the inspection door 13; at this time, the inspection door 13 does not need to pass through the cabinet 111 and no gap is reserved, that is, in this embodiment, at least a gap does not need to be reserved between the front side of the electrical cabinet 11 and the inspection door 13, so that the arrangement space of the electrical cabinet 11 is increased.

The inspection door 13 can be in sealing fit with the cabinet 111 to improve the sealing performance of the installation space, and further improve the dustproof and waterproof performance. In some examples, a seal 15 may be disposed between the inspection door 13 and the cabinet 111. The sealing member 15 may be made of an elastic material such as rubber. When the inspection door 13 is in the closed state, the sealing member 15 may be in a compressed state, so that the sealing member 15 can be in contact with the inspection door 13 and the cabinet 111 closely below, thereby filling a gap between the edge of the inspection door 13 and the cabinet 111 through the sealing member 15, thereby ensuring that external dust, liquid, and the like cannot enter the installation space from the gap between the inspection door 13 and the cabinet 111.

Alternatively, the seal 15 may be a ring-shaped structure that conforms to the shape of the inspection window 112. For example, when the inspection window 112 has a rectangular shape, the sealing member 15 has a rectangular ring shape. The seal 15 may be an integrally provided ring structure. Alternatively, the sealing member 15 may be a ring-shaped structure formed by splicing a plurality of sealing strips.

The carriage 1 that this embodiment provided, through being connected cabinet body 111 with the side wall 19 of carriage 1, one side and the built-in dividing wall 17 of inspection door 13 through locating cabinet body 111 inspection window 112 department with the lid are connected, inspection door 13 can also be connected with cabinet body 111 when being in the closed condition, so, need not between inspection door 13 and the cabinet body 111 to realize the installation to inspection door 13 at the reservation clearance, thereby make cabinet body 111 have relatively great placement space, make device or system's equipment that can arrange in the 11 internal cabinets bodies of regulator cubicle 111, in order to satisfy the development demand of rail transit technique.

In one possible implementation, as shown in fig. 5 and 7, the car 1 further includes a locking mechanism 132. The locking mechanism 132 is connected to the inspection door 13 and the cabinet 111. The locking mechanism 132 has a locked state and an unlocked state. Locking mechanism 132, when in a locked state, may be used to couple inspection door 13 with cabinet 111 such that inspection door 13 is in a closed state. With the locking mechanism 132 in the unlocked state, the inspection door 13 can be switched from the closed state to the open state.

Illustratively, the inspection door 13 has opposite first and second sides, with the first side being relatively closer to the sidewall 19. The first side can be pivotally connected to the interior partition 17 by at least one hinge, for example the first side can be pivotally connected to the interior partition 17 by two or three hinges spaced apart. The second side is connected to a locking mechanism 132.

In some examples, the locking mechanism 132 may be a three-point locking mechanism. The three-point locking mechanism may include an upper door lock 1321, a middle door lock 1322, and a lower door lock 1323 that are distributed in the vertical direction; wherein, the middle door lock 1322 can adopt a common lock structure; the middle door lock 1322 may be connected to the upper door lock 1321 and the lower door lock 1323 through an upper link and a lower link, respectively, so that the upper door lock 1321 and the middle door lock 1322 are controlled to be opened and closed simultaneously by the middle door lock 1322.

Illustratively, the middle door lock 1322 may include a lock housing, a lock cylinder, a transmission mechanism, a bolt, and an elastic member, the lock cylinder, the transmission mechanism, the bolt, and the elastic member are disposed in the lock housing, the lock housing may be disposed on the inspection door 13, and the cabinet 111 is provided with a lock hole cooperating with the bolt; the lock core can drive the lock tongue to enter and exit the lock hole through the transmission mechanism under the driving of the rotation movement of the key. For example, when the locking mechanism 132 needs to be switched to the unlocking state, the key inserted into the lock cylinder can drive the lock cylinder to rotate, and the transmission mechanism drives the lock tongue to slide out of the lock hole formed in the cabinet body 111 and retract into the lock case, so that the connection between the inspection door 13 and the cabinet body 111 is released, and at this time, the inspection door 13 can be opened; then, under the action of the elastic piece, the elastic piece can drive the bolt to extend out of the lock shell again, so that the bolt is in the initial position.

The lock tongue can be connected with a linkage piece, and the linkage piece can be connected to the upper connecting rod and the lower connecting rod; in the process that the bolt is contracted to the lock shell, the bolt drives the upper door lock 1321 and the lower door lock 1323 to move to an unlocking state through the linkage piece, the upper connecting rod and the lower connecting rod; in the process that the bolt extends out of the lock shell again, the bolt can drive the upper door lock 1321 and the lower door lock 1323 to restore to the initial positions through the linkage piece, the upper connecting rod and the lower connecting rod.

Of course, the specific structure and implementation process of the three-point locking mechanism are not limited thereto, and the embodiment is not limited thereto. The three-point locking mechanism can be of conventional construction or can be arranged by the person skilled in the art according to the actual requirements.

In other examples, locking mechanism 132 may be a conventional door lock structure; this may be accomplished similarly to the intermediate door latch 1322 of the previous example, in which case the latch structure does not require the provision of a linkage. At this time, the number of the door lock structures may be one, and the door lock structures may be disposed in the middle of the inspection door 13, so as to facilitate the operation of the operator. Of course, the locking mechanism 132 may be plural, and plural locking mechanisms 132 may be spaced apart in the vertical direction.

In one possible implementation, as shown in fig. 8 and 9, the seal 15 may slide relative to the cabinet 111 to enable the seal 15 to move toward the inspection door 13 or away from the inspection door 13.

Illustratively, the electrical cabinet 11 further includes an adjusting bolt and a nut. The sealing member 15 is provided with a plurality of long adjustment holes 153 distributed at intervals; the length direction of the adjustment long hole 153 is parallel to the front-rear direction. Illustratively, the sealing member 15 includes a ring-shaped sealing body 151, a connecting edge 152 extending rearward is provided at a rear side of the sealing body 151, and an adjustment long hole 153 is provided at the connecting edge 152.

The adjustment bolts are slidably disposed in the corresponding adjustment long holes 153, respectively. Bolt holes are formed in the corresponding positions of the cabinet body 111, and adjusting bolts penetrate through the bolt holes. A nut can be embedded in the cabinet body 111 in advance, at this time, the head of the adjusting bolt can be located on one side of the sealing element 15 departing from the cabinet body 111, and the rod part of the adjusting bolt sequentially penetrates through the adjusting long hole 153 and the bolt hole and can be matched with the nut; alternatively, the head of the adjusting bolt is located in the cabinet 111, and the rod of the adjusting bolt passes through the bolt hole and the adjusting long hole 153 in sequence and can be engaged with the nut.

The nut is adapted to cooperate with the adjusting bolt when the seal 15 is moved to a predetermined position relative to the cabinet 111, so as to securely connect the seal 15 to the cabinet 111. In this manner, the seal 15 is enabled to slide relative to the adjustment bolt, that is, the seal 15 is enabled to move toward the inspection door 13 or away from the inspection door 13 relative to the cabinet 111.

When the sealing member 15 moves to the preset position, the front side surface of the sealing member 15 can be in close contact with the inspection door 13, so that the sealing member 15 can be ensured to fill the gap between the edge of the inspection door 13 and the cabinet 111, and the sealing effect on the installation space is ensured. In addition, an adjusting long hole 153 may be formed in the cabinet 111, and a bolt hole may be formed in the sealing member 15, and the implementation process may be similar to that described above, and will not be described herein again.

During a specific operation, when there is a gap between the sealing member 15 and the inspection door 13, the nut or bolt can be loosened, and the sealing member 15 is controlled to move forward relative to the cabinet 111 until the sealing member 15 can abut against the inspection door 13, so as to ensure that the sealing member 15 can be in close contact with the inspection door 13. Of course, the interior partition wall 17 is also adjusted by a certain amount with respect to the vehicle body in a normal case, and the position of the interior partition wall 17 with respect to the vehicle body may be adjusted to ensure that the packing 15 and the inspection door 13 can be brought into close contact.

In addition, as shown in fig. 6, the electrical cabinet 11 further includes a sealing block 113, the sealing block 113 is provided with a wire hole through which a wire harness can pass, and the wire harness is connected to a device or equipment in the installation space; the cabinet body 111 is provided with an outlet, and the sealing block 113 is arranged at the outlet. Wherein, the sealing block 113 can be closely contacted with the inner wall at the wire outlet, and the sealing block 113 is also closely contacted with the wire harness penetrating through the sealing block; therefore, the condensed water in the air duct of the roof air conditioner can be prevented from dripping into the electrical cabinet 11 to influence the normal operation of internal system equipment and components. Wherein, the sealing block 113 can be made of rubber material; alternatively, the sealing block 113 may be formed of a sealant filled at the outlet.

In one possible implementation manner, as shown in fig. 10, the cabinet 111 includes a first fireproof frame 1111 and a first fireproof plate 1112, and the first fireproof plate 1112 is connected to the first fireproof frame 1111, so that the cabinet 111 can form a sealed installation space, which is favorable for achieving waterproof and dustproof functions. The first fire protection frame 1111 may be cube-shaped. The first fireproof frame 1111 may be formed by connecting a plurality of connection beams. The first fireproof plate 1112 can cover the first fireproof frame 1111; illustratively, the first flame retardant panel 1112 may be wrapped around an outer surface of the first flame retardant frame 1111 and/or the first flame retardant panel 1112 may be wrapped around an inner surface of the first flame retardant frame 1111 to provide sealing of the cabinet 111. Of course, the first flame retardant panel 1112 may also be attached to a plurality of connecting beams that make up the frame structure to block the space between the connecting beams, so that the cabinet 111 is sealed.

The first fireproof frame 1111 and the first fireproof plate 1112 may be made of fireproof materials such as stainless steel plates. Thus, when a fire breaks out in the electrical cabinet 11, the first fireproof frame 1111 and the first fireproof wall 1112 can block the fire from spreading outward. In addition, the first fireproof frame 1111 and the first fireproof plate 1112 made of stainless steel have good strength, so that the cabinet 111 has certain bearing performance.

Optionally, the cabinet 111 is provided with a first insulating plate 1113 towards the inner side of the installation space, so that the cabinet 111 has electrical insulating property to avoid electrical connection between the cabinet 111 and components inside the cabinet. In addition, the first insulating plate 1113 may also have corrosion resistance, ultraviolet resistance, and the like. Illustratively, the first flame retardant panel 1112 may be skin-clad to an inner surface of the first flame retardant frame 1111; the first insulating plate 1113 is disposed on an inner surface of the first flame retardant plate 1112.
