Abstract
Description
Technical Field
[0001] This application relates to rail vehicle structural technology, and more particularly to a carriage and rail vehicle. Background Technology
[0002] Passenger rail vehicles have multiple windows on their side walls, with the window glass fixed to the vehicle body by adhesive or bolts. As the vehicle operates for a long time, the adhesive-bonded windows may detach and fall off due to the failure of the adhesive.
[0003] A common method is: such as Figure 1 As shown, the inner side of the window 2 is bonded to the vehicle frame 1 with adhesive 3. Sealant 4 is filled between the end face of the window 2 and the vehicle frame 1, and it abuts against the surface of the adhesive 3, thus sealing the window 2 to the vehicle frame 1. However, in this design, if the adhesive 3 fails, the window 2 will detach directly from the vehicle frame 1. Furthermore, since the sealant 4 is exposed on the outside of the vehicle, it requires regular inspection and replacement. During the replacement of the sealant 4, it needs to be cut and peeled off, which can damage the adhesive 3, leading to a failure in the connection between the window 2 and the vehicle frame 1, further increasing the likelihood of the window 2 detaching from the vehicle frame 1. Summary of the Invention
[0004] To address one of the aforementioned technical deficiencies, this application provides a carriage and a rail vehicle.
[0005] According to a first aspect of the embodiments of this application, a carriage is provided, comprising:
[0006] The vehicle frame has windows, and the vehicle frame on both sides of the windows extends toward the windows to form an outer mounting part and an inner mounting part, with a gap between the outer mounting part and the inner mounting part.
[0007] A vehicle window includes an inner glass layer and an outer glass layer, which are connected as a single structure. In any direction of the vehicle window, the length of the inner glass layer is greater than the length of the outer glass layer. The longer end of the inner glass layer is embedded in the gap between the outer mounting part and the inner mounting part, and the outer mounting part restricts both ends of the inner glass layer within the gap.
[0008] Adhesive is used to fill the space between the inner surface of the inner glass layer and the inner mounting part;
[0009] The sealant is placed between the outer glass and the outer mounting part, and presses inward against the outer surface of the inner glass.
[0010] As described above, in the carriage, the body frame at the top of the window extends downward to form an upper inner mounting part and an upper outer mounting part, with a gap between the upper inner mounting part and the upper outer mounting part; the body frame at the bottom of the window extends upward to form a lower inner mounting part and a lower outer mounting part, with a gap between the lower inner mounting part and the lower outer mounting part.
[0011] In the vertical direction, the top of the inner glass layer is higher than the top of the outer glass layer, and the bottom of the inner glass layer is lower than the bottom of the outer glass layer; the top of the inner glass layer is embedded in the gap between the upper inner mounting part and the upper outer mounting part, and the top of the inner glass layer is higher than the bottom of the upper outer mounting part; the bottom of the inner glass layer is embedded in the gap between the lower inner mounting part and the lower outer mounting part, and the bottom of the inner glass layer is lower than the top of the lower outer mounting part.
[0012] As described above, the adhesive is filled between the top inner surface of the inner glass and the upper inner mounting portion, and between the bottom inner surface of the inner glass and the lower inner mounting portion.
[0013] As described above, the sealant is disposed between the top of the outer glass and the upper outer mounting part, and abuts inward against the outer surface of the inner glass; and is disposed between the bottom of the outer glass and the lower outer mounting part, and abuts inward against the outer surface of the inner glass.
[0014] As described above, the carriage uses two pieces of adhesive, which are sequentially placed between the inner surface of the inner glass and the inner mounting part along the installation direction.
[0015] As described above, the end of the inner mounting part of the adhesive on the outer side of the carriage is flush with the surface of the carriage.
[0016] As described above, the outer surface of the outer glass of the carriage is flush with the outer surface of the outer mounting part.
[0017] As described above, the outer end face of the sealant in the carriage is flush with the outer surface of the outer glass.
[0018] As described above, the car body frame of the carriage is a side wall frame.
[0019] According to a second aspect of the embodiments of this application, a rail vehicle is provided, including: a carriage as described above.
[0020] The technical solution provided in this application embodiment includes a vehicle frame with a window. The vehicle frame on both sides of the window extends towards the window to form an outer mounting portion and an inner mounting portion, with a gap between the outer mounting portion and the inner mounting portion. The window includes an inner glass layer and an outer glass layer, which are connected as a single unit. In any direction of the window, the length of the inner glass layer is greater than the length of the outer glass layer. The longer end of the inner glass layer is embedded in the gap between the outer mounting portion and the inner mounting portion, and the outer mounting portion restricts both ends of the inner glass layer within this gap. Adhesive fills the inner layer... Between the inner surface of the glass and the inner mounting part; the sealant is placed between the outer glass and the outer mounting part, and presses inward against the outer surface of the inner glass. The cooperation between the inner glass and the outer mounting part limits the window and prevents the window from falling off the vehicle frame under natural conditions. In addition, the inner glass separates the adhesive and the sealant. The sealant no longer comes into contact with the adhesive, making it easier to cut and peel off the sealant during disassembly without damaging the adhesive. This improves the service life of the adhesive and ensures the firmness of the connection between the window and the vehicle body. Attached Figure Description

[0035] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
[0036] like Figure 2 and Figure 3 As shown, this embodiment provides a carriage that can be applied to rail vehicles, especially passenger cars. The carriage includes a car body and a floor and interior structure installed on the car body. The car body is composed of a chassis, side walls, a roof, and end walls. The carriage is equipped with windows, which can be installed on the side walls or end walls.
[0037] The vehicle body includes a vehicle frame, an inner skin disposed inside the vehicle frame, and an outer skin disposed outside the vehicle frame. The vehicle frame 1 has a window cut out at the location where the window needs to be installed. The vehicle frame on both sides opposite the window extends towards the window to form an outer mounting part 11 and an inner mounting part 12, with a gap between the outer mounting part 11 and the inner mounting part 12.
[0038] The car window consists of an outer glass layer 21 and an inner glass layer 22. The outer glass layer 21 and the inner glass layer 22 are connected as a single structure, which can be achieved using existing technology. The outer glass layer 21 and the inner glass layer 22 have a hollow structure, which has good thermal insulation performance.
[0039] In any direction of the window, the length of the inner glass 22 is greater than the length of the outer glass 21. Figure 2 For example, the inner glass 22 is longer than the outer glass 21 in the left-right direction, and the outer glass 21 is equal to the inner glass 22 in the up-down direction. Alternatively, the inner glass 22 is longer than the outer glass 21 in the up-down direction, and the outer glass 21 and inner glass 22 are equal in the left-right direction.
[0040] The longer end of the inner glass 22 is embedded in the gap between the outer mounting portion 11 and the inner mounting portion 12, and the outer mounting portion 11 restricts both ends of the inner glass 22 within this gap. If the length of the inner glass 22 in the left-right direction is longer, the left and right ends of the inner glass 22 are embedded in the gap between the outer mounting portion 11 and the inner mounting portion 12 on both sides of the window in the left-right direction, and the outer mounting portion 11 on both sides of the window in the left-right direction limits the inner glass 22, preventing the window from detaching from the window. If the length of the inner glass 22 in the vertical direction is longer, the upper and lower ends of the inner glass 22 are embedded in the gap between the outer mounting portion 11 and the inner mounting portion 12 on both sides of the window in the vertical direction, and the outer mounting portion 11 on both sides of the window in the vertical direction limits the inner glass 22, preventing the window from detaching from the window.
[0041] Adhesive 3 is filled between the inner surface of the inner glass 22 and the inner mounting part 12, firmly bonding the inner glass 22 to the vehicle body. Specifically, the inner glass 22 can be bonded to the vehicle frame only at the longer end using adhesive, or all four ends of the inner glass 22 can be bonded to the vehicle frame using adhesive to improve the connection strength between the window and the vehicle frame.
[0042] The sealant 4 is positioned between the outer glass layer 21 and the outer mounting part 11, and abuts inward against the outer surface of the inner glass layer 22. On one hand, the sealant 4 fills the gap between the outer glass layer 21 and the outer mounting part 11, sealing the gap and preventing external particles and moisture from entering the vehicle compartment. On the other hand, the sealant 4 is made of a material with a certain degree of deformation, such as rubber, which increases the friction with the outer glass layer 21 and the outer mounting part 11, thereby improving the firmness of the connection between the window and the vehicle body. Furthermore, the end of the sealant 4 inserted into the window abuts against the outer surface of the inner glass layer 21, separating the adhesive 3 from the sealant 4. Since the sealant 4 no longer comes into contact with the adhesive 3, it is easier to cut and peel off the sealant 4 during disassembly without damaging the adhesive 3, thus extending the service life of the adhesive 3 and ensuring the firmness of the connection between the window and the vehicle body.
[0043] For the flush ends of the inner glass 22 and the outer glass 21, a barrier can be placed between the sealant 4 and the adhesive 3 to separate the sealant 4 and the adhesive 3 without affecting the removal of the sealant 4. For example, the barrier can be made of soft foam.
[0044] The technical solution provided in this embodiment includes a window on the vehicle frame. The vehicle frame on both sides of the window extends towards the window to form an outer mounting portion and an inner mounting portion, with a gap between the outer mounting portion and the inner mounting portion. The window includes an inner glass layer and an outer glass layer, which are connected as a single unit. In any direction of the window, the length of the inner glass layer is greater than the length of the outer glass layer. The longer end of the inner glass layer is embedded in the gap between the outer mounting portion and the inner mounting portion, and the outer mounting portion restricts both ends of the inner glass layer within this gap. Adhesive fills the inner glass layer. Between the inner surface of the glass and the inner mounting part; the sealant is placed between the outer glass and the outer mounting part, and presses inward against the outer surface of the inner glass. The cooperation between the inner glass and the outer mounting part limits the window and prevents the window from falling off the vehicle frame under natural conditions. In addition, the inner glass separates the adhesive and the sealant. The sealant no longer comes into contact with the adhesive, making it easier to cut and peel off the sealant during disassembly without damaging the adhesive. This improves the service life of the adhesive and ensures the firmness of the connection between the window and the vehicle body.
[0045] Even after the adhesive 3 fails, the vehicle frame 1, due to the influence of wind pressure inside and outside the vehicle, obstructs the inner glass layer 22 in the width direction, preventing the window from being directly detached from the vehicle frame 1. During the disassembly and assembly process, the window is installed and removed by moving it in the height direction and applying a tilt angle through the gap in the reserved sealant 4 installation area.
[0046] Based on the above technical solution, this embodiment provides a specific implementation method: as follows Figure 3 , Figure 4 and Figure 5 As shown, the upper and lower ends of the window are fitted with the vehicle body for limiting, that is: the vehicle body frame 1 at the top of the window extends downward to form an upper inner mounting part 14 and an upper outer mounting part 13, with a gap between the upper inner mounting part 14 and the upper outer mounting part 13. The vehicle body frame 1 at the bottom of the window extends upward to form a lower inner mounting part 16 and a lower outer mounting part 15, with a gap between the lower inner mounting part 16 and the lower outer mounting part 15.
[0047] In the vertical direction, the top of the inner glass layer 22 is higher than the top of the outer glass layer 21, and the bottom of the inner glass layer 22 is lower than the bottom of the outer glass layer 21; the top of the inner glass layer 22 is embedded in the gap between the upper inner mounting portion 14 and the upper outer mounting portion 13, and the top of the inner glass layer 22 is higher than the bottom of the upper outer mounting portion 13; the bottom of the inner glass layer 22 is embedded in the gap between the lower inner mounting portion 16 and the lower outer mounting portion 15, and the bottom of the inner glass layer 22 is lower than the top of the lower outer mounting portion 15.
[0048] During the window installation process, the window is tilted, and the top of the inner glass 22 is first inserted into the gap between the upper inner mounting part 14 and the upper outer mounting part 13, and then moved upwards to approximately the limit position. Figure 6 and Figure 7 As shown. Then the bottom end of the inner glass 22 can enter the gap between the lower inner mounting part 16 and the lower outer mounting part 15, as shown. Figure 6 and Figure 8 As shown. Then straighten the car window and move it down to the installation position. Inside the car, apply the adhesive 3 between the inner glass 22 and the upper inner mounting part 14 and the lower inner mounting part 16. Outside the car, insert the sealant 4 between the upper outer mounting part 13, the lower outer mounting part 15 and the outer glass 21, and press it against the outer surface of the inner glass 22.
[0049] During the operation of the rail vehicle, the sealant 4 exposed on the outside of the carriage is periodically inspected. When replacement is needed, the sealant 4 is cut off and replaced with new sealant 4. The adhesive 3 is not exposed on the outside of the carriage, and its replacement frequency is lower.
[0050] During the window removal process, all sealant 4 is removed from the outside of the vehicle, and all adhesive 3 is removed from the inside of the vehicle. Then, the window is moved upward and tilted so that the lower end of the inner glass 22 is removed from the window first, and then the window is moved downward so that the upper end of the inner glass 22 is also removed from the window.
[0051] Based on the above, adhesive 3 is filled between the top inner surface of the inner glass 22 and the upper inner mounting portion 14, and between the bottom inner surface of the inner glass 22 and the lower inner mounting portion 16.
[0052] The sealant 4 is disposed between the top end of the outer glass 21 and the upper outer mounting portion 13, and abuts inward against the outer surface of the inner glass 22; and is disposed between the bottom end of the outer glass 21 and the lower outer mounting portion 15, and abuts inward against the outer surface of the inner glass 22.
[0053] Furthermore, two pieces of adhesive 3 are used, sequentially placed between the inner surface of the inner glass 22 and the inner mounting part along the installation direction. During installation, one piece of adhesive 3 is inserted first, and then another piece is inserted on the outside, with the surface of the outer adhesive 3 exposed to the interior environment of the vehicle. After the vehicle has been in operation for a period of time, the outer adhesive 3 may suffer damage or corrosion and need to be replaced. In this case, only the outer adhesive 3 needs to be replaced, while the inner adhesive 3 still ensures a firm connection between the window and the vehicle body, and also reduces maintenance costs.
[0054] One specific solution is that the end of the inner mounting part 12 of the adhesive 3 located on the outside is flush with the outer surface of the outer glass 21 and the outer surface of the outer mounting part 11 is flush with the outer surface of the outer glass 21, and the outer end face of the sealant 4 is flush with the outer surface of the outer glass 21, which has a better visual effect and is easier to operate.
[0055] If the aforementioned car window can be installed on the side wall as a side window, then the car body frame 1 is the side wall frame.
[0056] The above solution utilizes the matching of the inner glass 22 size with the vehicle body structure to prevent the window from being blocked inside the vehicle body when there is a risk of adhesive 3 failure. This eliminates the need for an additional aluminum frame, preventing the window from easily coming off and avoiding accidental injury, while also reducing the weight of the window itself.
[0057] The inner glass 22 of the car window has made certain divisions between the sealant 4 and the adhesive 3. The most suitable model can be selected according to the characteristics of the sealant 4 and the adhesive 3 to bond and seal the car window, which is cheaper, more effective and more convenient to maintain.
