Detailed Description
The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings. The following description of the embodiments of the present invention with reference to the accompanying drawings is intended to explain the general inventive concept and should not be construed as limiting the invention.
Furthermore, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the embodiments. It may be evident, however, that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and devices are not shown in order to simplify the drawing.
FIG. 1 illustrates an overall perspective view of the inner and outer windshield assemblies. The outer and inner windshield assemblies 20, 10 are disposed between two adjacent compartments (not shown) of the vehicle, forming part of a junction between the two compartments.
As an example, both ends of the outer windshield assembly 20 are respectively connected to the bodies of the adjacent cars, and the outer windshield assembly 20 itself and the connection between the outer windshield assembly and the car bodies are air-tight and thus air-tightly isolated from the outside to resist pressure waves caused by changes in air pressure on the surface of the car body when the train is operated at high speed, and to isolate the inside of the train from the outside and prevent external dust and sand from entering the inside of the train.
As shown in fig. 1, the junction between the two cars further includes a cab apron assembly 30 having both ends disposed on the floor of the two cars, respectively, for passengers to pass therethrough and to be transferred from one car to the other.
Although the car body is not shown in fig. 1, those skilled in the art will appreciate that the inner damper assembly 10, the outer damper assembly 20 and the car bodies on both sides together form a closed space therebetween, and the volume of the closed space changes sharply during a curve or turn of the train, so that the pressure difference on both sides of the inner damper 1 in the inner damper assembly 10 changes greatly, causing deformation of the inner damper 1, which further affects the pressure change in the car, causing discomfort to passengers, such as ears.
At least in order to solve the problem, as an example, a flow guide device is provided on the inner windshield 1 so that an air current can flow from one side of the inner windshield 1 to the other side via the flow guide device, thereby reducing a difference in air pressure between both sides of the inner windshield and reducing discomfort of passengers due to turning.
As shown in fig. 3, the deflector 2 includes a deflector hole 25 penetrating the inner windshield 1, and air flows from one side of the inner windshield 1 to the other side through the deflector hole 25. It will be appreciated by those skilled in the art that the deflector only comprises deflector holes 25 for the purpose of reducing the air pressure differential across the inner windscreen 1.
It will be appreciated by those skilled in the art that the deflector 2 may be provided at any location on the inner windscreen 1 in order to reduce the air pressure differential across the inner windscreen 1 and is not limited to the location shown in figure 1. The flow guide device 2 can be arranged on the inner windshield with any structure as long as the space between the inner side and the outer side of the inner windshield can be communicated, and the number of the flow guide devices can be one or more than one, and the flow guide devices can be arranged at different positions on the inner windshield as required. Thus, although a double inner windshield is described below, it will be understood by those skilled in the art that the inner windshield structure is not limited thereto, and the inventive concept is equally applicable to a single inner windshield structure.
Since the air pressure changes rapidly when the train runs at a high speed, the high-speed flow of the air flow in the diversion holes 25 generates a squeaking sound, and the noise also affects the comfort of passengers. Therefore, as an example, a sound-absorbing device 21 formed of a sound-absorbing material is provided in the guide hole 25 to absorb the squeal generated when the air passes through the guide device, thereby preventing the noise generated by the guide device. The sound absorber 21 may be, for example, an integral sound absorbing block inserted into the diversion hole 25, or may be a combination of sound absorbing materials of other forms.
The inner windshield performs the expanding and contracting movement due to the pressure difference between both sides, and therefore, the sound-absorbing device 21 disposed in the diversion hole has a risk of falling, and in order to avoid this risk, as an example, end plates are respectively provided at both ends of the diversion hole 25, on both sides of the sound-absorbing device 21, to keep the sound-absorbing device 21 from falling. The arrangement of the two end plates (hereinafter, the first perforated plate 22 and the second perforated plate 23) will be described below by taking a double-layer internal windshield assembly as an example.
Figure 3 shows a schematic partial cross-sectional view of a double inner windshield 1. The double-layer inner windshield 1 comprises an inner folding shed 11 and an outer folding shed 12, the inner folding shed 11 comprises a middle frame 111, the outer folding shed 12 comprises a middle frame 121, and the diversion holes 25 penetrate through the inner folding shed 11 and the outer folding shed 12, so that air can circulate between the space inside the inner folding shed 11 (on the left side in fig. 3) and the space outside the outer folding shed 12 (on the right side in fig. 3), and the pressure difference between the two sides of the inner windshield assembly 10 is eliminated.
As an example, the deflector 2 further includes a first perforated plate 22 and a second perforated plate 23, the first perforated plate 22 being fixed to the outer bellows 12 at one end (right-side end in fig. 3) of the deflector hole 25; the second perforated plate 23 is fixed to the inner bellows 11 at the other end (left end in fig. 3) of the diversion hole 25, and the first perforated plate 22 and the second perforated plate 23 hold the sound absorbing device 21 therebetween. The first perforated plate 22 and the second perforated plate 23 are each provided with a through hole 221 for air to flow through, so that the air flows from the space between the outer bellows 12 and the outer windshield assembly 20 through the first perforated plate 22, passes through the sound-absorbing material of the sound-absorbing device 21 provided in the diversion hole 25, and flows through the second perforated plate 23, and enters the space inside the inner bellows 11, i.e., the interior of the vehicle compartment, and vice versa.
The provision of the two end plates, i.e. the first and second perforated plates 22, 23, keeps the sound absorbers 21 whilst not affecting the air flow inside and outside the windscreen 1.
As an example of the arrangement of the through holes on the first and second perforated plates 22 and 23, a plurality of through holes 221 may be included thereon. Fig. 2 shows a partially enlarged schematic view of part a of fig. 1, wherein the second perforated sheet 22 is shown to be provided with through holes 221, by way of example, the through holes 221 may be oblong holes.
As shown in fig. 4, the plurality of through holes 221 may be arranged in a plurality of rows, wherein the through holes of adjacent rows are arranged alternately in the height direction of the inner windshield. This arrangement of the through-holes helps the air to enter the deflector hole uniformly over the cross-section of the deflector hole.
It will be appreciated by those skilled in the art that the through-holes 221 may be of other shapes and arrangements as long as they allow air to circulate inside and outside the inner windshield 1.
Due to the bellows-like shape of the inner windshield, in order to facilitate the fixing of the first perforated plate 22 and the second perforated plate 23, the first perforated plate 22 and the second perforated plate 23 may be fixed to the middle frame 111 of the inner bellows 11 and the middle frame 121 of the outer bellows 12, respectively. The fixing of the perforated plate to the intermediate frame can be effected by means of fasteners, such as screws, bolts or the like.
As an example, the deflector 2 may further include a guide duct (not shown) disposed in the deflector hole 25, in which the sound absorbing device 21 is disposed, the guide duct being disposed such that the sound absorbing device 21 is more securely held and air is better guided from one side of the inner damper to the other side, avoiding the air from entering the space between the inner bellows and the outer bellows in the case of using the double inner damper.
It will be appreciated by those skilled in the art that although the provision of sound absorbers and the use of first and second perforated plates are described herein as examples, the present invention may be practiced without sound absorbers or without first and second perforated plates and serves to reduce the pressure differential across the interior windshield and to reduce occupant discomfort caused by such pressure differential.
In the inner windshield assembly of the utility model, the flow guide device is arranged on the inner windshield to communicate the spaces at two sides of the inner windshield, thereby reducing the pressure difference at two sides of the inner windshield and reducing the discomfort of passengers and the damage to the inner windshield caused by the pressure difference; furthermore, the sound absorption device arranged in the flow guide hole can absorb the squeaking sound generated when air passes through the flow guide device, so that the noise generated by the flow guide device is avoided; the first perforated plate and the second perforated plate can firmly keep the sound absorption device, so that the sound absorption device is prevented from falling off, and the flow guide device can stably play a role; the specific arrangement of the through holes on the first and second perforated plates enables air to uniformly circulate in the flow guide holes, so that better circulation and sound absorption effects are realized.
The utility model discloses still relate to a vehicle including two at least carriages, this vehicle is including setting up the connecting portion between two adjacent carriages. The connecting portion includes the outer windshield assembly 20 and the inner windshield assembly 10 as described above, and the vehicle thus has the advantages of the inner windshield assembly having the above-described structure, and the riding comfort of the vehicle and the life of the inner windshield are improved.
Although a few embodiments of the present invention have been shown and described, it would be appreciated by those skilled in the art that changes may be made in these embodiments without departing from the principles and spirit of the general inventive concept, the scope of which is defined in the claims and their equivalents.
