Description
Technical Field
[0001] This application relates to the field of vehicle manufacturing technology, and in particular to a brush structure and a rail vehicle. Background Technology
[0002] Rail transit vehicles have become an important mode of transportation for people. Their development not only focuses on faster and more convenient travel efficiency but also emphasizes the safety and comfort of vehicle operation. Among these features, the connecting passageway is a retractable "bridge" linking two subway cars. It allows passengers and crew to safely pass between cars while the train is in motion. Since the interior of the connecting passageway directly faces passengers, its safety is paramount. Currently, a brush structure is designed between the connecting passageway and the car body. This structure primarily prevents passengers from inserting their fingers into the gap between the connecting passageway and the car body, thus preventing injuries.
[0003] However, with the existing brush structure, vibrations during vehicle movement can easily cause the connection between the brush structure and the vehicle body to loosen, leading to the brush structure detaching from the vehicle body. Summary of the Invention
[0004] This application proposes a brush structure to prevent the connection between the brush structure and the vehicle body from loosening due to vibration caused by the buffer baffle.
[0005] To achieve the above objectives, this application discloses the following technical solutions:
[0006] In a first aspect, this application provides a brush structure, which includes: a shielding component, a support, and a connecting component;
[0007] The shielding assembly includes: a brush and a buffer baffle; the bracket is a one-piece molded structure, at least a portion of the bracket is configured as a mounting groove, a first side edge of the brush is mounted in the mounting groove, and a second side edge of the brush is suspended.
[0008] The connecting assembly includes: a first connector and a second connector, wherein the first connector mounts the buffer baffle to the bracket, and the side edge of the buffer baffle opposite to the second side edge of the brush is suspended; the second connector is used to mount the bracket to the vehicle body, and when the bracket is mounted to the vehicle body, at least one of the brush and the buffer baffle is in contact with the through channel.
[0009] In some embodiments, the portion of the bracket configured as a mounting groove is a first part of the bracket; the second part of the bracket is configured as a mounting portion, and a first connector mounts a buffer baffle to the mounting portion.
[0010] In some embodiments, the third portion of the bracket is configured as a mounting plate, and the second connector is used to mount the mounting plate to the vehicle body.
[0011] In some embodiments, the second part of the bracket protrudes along the normal direction of the mounting plate to form a mounting portion, a mounting groove is provided on the top of the mounting portion, and the first connector mounts the buffer baffle on the side of the mounting portion.
[0012] In some embodiments, the first connector mounts the buffer baffle to the mounting portion along the second direction;
[0013] The second connector mounts the mounting plate onto the vehicle body along the first direction; wherein the first direction and the second direction are perpendicular.
[0014] In some embodiments, the interior of the mounting part is a hollow cavity, and the first connector is a first fastener;
[0015] After the fastening end of the first fastener passes through the buffer baffle and the side peripheral wall of the mounting part in sequence, the part where the fastening end passes through the side peripheral wall of the mounting part is located in the hollow cavity.
[0016] In some embodiments, the brush structure further includes: a pressure strip;
[0017] The first fastener passes through the pressure strip and the buffer baffle in sequence and is fastened to the mounting part.
[0018] In some embodiments, the brush is elongated in shape;
[0019] The buffer baffle is a rubber baffle and is long and narrow. The side opposite to the second edge of the buffer baffle and the brush is the first side of the buffer baffle. The first side of the buffer baffle and the second side of the brush are matched in shape and size.
[0020] In some embodiments, the number of first connectors is multiple, and the multiple first connectors mount the buffer baffle to the bracket;
[0021] And / or, the number of second connectors is multiple, and multiple second connectors are used to mount the bracket to the vehicle body.
[0022] In some embodiments, the brush is tilted relative to the mounting plate; and / or the buffer baffle is tilted relative to the mounting plate.
[0023] Secondly, this application provides a rail vehicle, including: a brush structure, a car body, and a through passage, wherein the brush structure is as described above.
[0024] As can be seen from the above technical solution, this brush structure, because the buffer baffle and the bracket are fixed by different connectors, compared with the existing technology (where the same connector passes through the buffer baffle and the bracket in sequence and is fixed to the vehicle body, and the buffer baffle is vibrated, causing the connector and the vehicle body to loosen, resulting in the separation of the buffer baffle, the bracket and the vehicle body), the vibration of the buffer baffle does not affect the fixation between the bracket and the vehicle body, making the connection structure between the bracket and the vehicle body stable and preventing the brush structure from falling off the vehicle body during use.
[0025] The present invention also provides a rail vehicle, which has corresponding beneficial effects due to the use of a brush structure, as can be seen from the previous description, and will not be repeated here. Attached Figure Description

[0034] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. The described embodiments are only a part of the embodiments of the present application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present application without inventive effort are within the scope of protection of the present application.
[0035] For the purposes of this application, the following structures are described in detail with reference to the accompanying drawings:
[0036] like Figures 1 to 3 As shown, this application provides a brush structure, which may include: a shielding component, a support 3, and a connecting component.
[0037] like Figure 1 As shown, the shielding assembly may include: a brush 1 and a buffer baffle 2; the bracket 3 is an integrally molded structure. Since the bracket 3 is an integrally molded structure, it ensures the overall structure is firm. At least a part of the bracket 3 is constructed as a mounting groove 31. The first side edge of the brush 1 is installed in the mounting groove 31, and the second side edge of the brush 1 is suspended.
[0038] like Figure 1 As shown, the connecting assembly may include: a first connector 5 and a second connector 6. The first connector 5 mounts the buffer baffle 2 to the bracket 3, and the side edge of the buffer baffle 2 opposite to the second side edge of the brush 1 is suspended. The second connector 6 is used to mount the bracket 3 to the vehicle body 7, and when the bracket 3 is mounted on the vehicle body 7, at least one of the brush 1 and the buffer baffle 2 is in contact with the through channel.
[0039] In the above technical solution, the first edge of the brush 1 is installed in the mounting groove 31. The buffer baffle 2 is installed on the bracket 3 using the first connector 5, so that the brush structure forms an integral structure. Then, the bracket 3 is installed on the vehicle body 7 using the second connector 6. After the bracket 3 is installed on the vehicle body 7, at least one of the brush 1 or the buffer baffle 2 is in contact with the through channel 8 to cover the gap between the through channel 8 and the vehicle body, preventing passengers from inserting their fingers into the gap and causing pinching injuries.
[0040] In addition, for example, Figure 4 and Figure 5 As shown, the side of the brush 1 away from the buffer baffle 2 is in contact with the through channel 8 to cover the gap between the through channel 8 and the vehicle body. During use, if the brush 1 is subjected to the squeezing force of the through channel 8, the second side edge of the brush 1 is in contact with the suspended side edge of the buffer baffle 2, so that the buffer baffle 2 can relieve the squeezing force on the brush 1 and protect the brush 1.
[0041] It should also be noted that, since the buffer baffle 2 and the bracket 3 are fixed by different connectors, compared with the existing technology (where the same connector passes through the buffer baffle and the bracket in sequence and is fixed to the vehicle body, and the buffer baffle is vibrated, causing the connector and the vehicle body to loosen, resulting in the separation of the buffer baffle, the bracket and the vehicle body), the vibration of the buffer baffle 2 does not affect the fixation between the bracket 3 and the vehicle body 7, making the connection structure between the bracket 3 and the vehicle body 7 stable and preventing the brush structure from falling off the vehicle body 7 during use.
[0042] To make the connection structure between the buffer baffle 2 and the bracket 3 more stable, such as Figure 1 As shown, the portion of the bracket 3 that is configured as the mounting groove 31 is the first part of the bracket 3; the second part of the bracket 3 is configured as the mounting portion 32, and the first connector 5 mounts the buffer baffle 2 to the mounting portion 32. In this technical solution, if the buffer baffle 2 is subjected to vibration during use, it will only be transmitted to the first connector 5, thus avoiding loosening between the bracket 3 and the vehicle body 7.
[0043] To ensure a secure and stable connection between the bracket 3 and the vehicle body 7, the third part of the bracket 3 is constructed as a mounting plate 33, and the second connector 6 is used to mount the mounting plate 33 onto the vehicle body 7. The mounting plate 33 has a larger contact area with the vehicle body 7, which facilitates the rapid installation of the brush structure and the vehicle body 7, and makes the connection between them more robust.
[0044] Based on the above solution, in order to ensure that the overall structure of the brush is more robust and stable, such as Figure 1 As shown, the second part of the bracket 3 protrudes along the normal direction of the mounting plate 33 to form a mounting part 32. A mounting groove 31 is provided on the top of the mounting part 32, and the first connector 5 installs the buffer baffle 2 on the side of the mounting part 32. Preferably, the opening direction of the mounting groove 31 is set at an angle to the normal direction of the mounting plate 33, so that the brush 1 installed in the mounting groove 31 is arranged at an angle.
[0045] To avoid mutual interference between the connectors during their connection process, such as Figure 1 As shown, the first connector 5 installs the buffer baffle 2 onto the mounting part 32 along the second direction.
[0046] The second connector 6 mounts the mounting plate 33 onto the vehicle body 7 along the first direction; wherein the first direction and the second direction are perpendicular. Specifically, after the first connector 5 mounts the buffer baffle 2 onto the mounting part 32 along the second direction, the second connector 6 mounts the mounting plate 33 onto the vehicle body 7 along the first direction, thus mounting the entire brush structure onto the vehicle body 7. It should be noted that because the connectors are connected in different directions, the connecting parts are located at different parts of the bracket 3 and are at a certain distance, which is beneficial to the stability and firmness of the overall structure of the bracket 3.
[0047] In order to accommodate different lengths of the first connector 5, such as Figure 1 The interior of the mounting part 32 is a hollow cavity, and the first connector 5 is the first fastener.
[0048] The fastening end of the first fastener passes through the buffer baffle 2 and the side wall of the mounting portion 32 in sequence, and the portion of the fastening end that passes through the side wall of the mounting portion 32 is located inside the hollow cavity. In this technical solution, the first fastener, after passing through the buffer baffle 2 and the side wall of the mounting portion 32 in sequence, fixes the buffer baffle 2 to the bracket 3. Thus, if the first fastener is too long, the excess portion passes through the side wall of the mounting portion 32 and is located inside the hollow cavity. Preferably, the first fastener is a bolt or screw.
[0049] To ensure a more robust and stable structure between the mounting section 32 and the buffer baffle 2, the brush structure may include a pressure strip 4.
[0050] The first fastener passes through the pressure strip 4 and the buffer baffle 2 in sequence and is secured to the mounting part 32. Specifically, the mounting part 32, the buffer baffle 2, and the pressure strip 4 are all provided with threaded through holes in their respective parts. The first fastener passes through the threaded through holes in sequence to fix the mounting part 32, the buffer baffle 2, and the pressure strip 4. In addition, the pressure strip 4 can distribute the pressure of the first fastener and protect the buffer baffle 2.
[0051] In order to conceal the long, narrow gap between the vehicle body 7 and the passageway 8, such as Figure 1 As shown, the shape of brush 1 is long and narrow.
[0052] The buffer baffle 2 is a rubber baffle, and it is elongated. The side opposite to the second edge of the brush 1 is the first side of the buffer baffle 2, and the shape and size of the first side of the buffer baffle 2 match the second side of the brush 1. In this technical solution, when the brush 1 is squeezed, the rubber baffle can provide all-round buffer protection for the brush 1.
[0053] To ensure the stability and firmness of the connection structure between the buffer baffle 2 and the bracket 3, multiple first connecting members 5 are used to install the buffer baffle 2 onto the bracket 3. Preferably, the multiple first connecting members 5 are arranged and connected along the length direction of the bracket 3, wherein the first connecting member 5 is a first fastener, which is a bolt or screw, and the bracket 3 has multiple through holes along its length for the first fasteners to pass through.
[0054] Similarly, to ensure the stability and firmness of the connection structure between the second connector 6 and the bracket 3, multiple second connectors 6 are used to install the bracket 3 onto the vehicle body 7. Preferably, multiple second connectors 6 are arranged and connected along the length of the bracket 3, wherein the second connector 6 is a second fastener, which is a bolt or screw, and the bracket 3 has multiple through holes along its length for the second fasteners to pass through; it should also be noted that, since bolts or screws are used to connect and fix the bracket to the vehicle body 7, a corresponding torque can be applied to the bolts or screws as needed.
[0055] Furthermore, the brush 1 includes a first portion mounted in the mounting groove and a second portion extending outward from the first portion, the second portion being inclined relative to the first portion; the buffer baffle 2 includes a first portion for mounting on the bracket 3 and a second portion extending outward from the first portion, the second portion being inclined relative to the first portion. Thus, the brush 1 is inclined relative to the mounting plate 33; and / or the buffer baffle 2 is inclined relative to the mounting plate 33, such as... Figures 3 to 5 As shown in the diagram, during the movement of the rail vehicle, the through channel 8 will move relative to the brush 1, as indicated by the arrow. When the through channel 8 moves closer to the brush 1, the direction of movement of the through channel is consistent with the tilt direction of the brush 1 and the buffer baffle 2. The external force borne by the brush 1 and the buffer baffle 2 is consistent with their own extension direction, so the force is small, and it is not easy to damage the brush 1 and the buffer baffle 2, thus extending the service life of the brush structure.
[0056] Furthermore, after the brush structure is installed on the vehicle body, the brush 1 first contacts the through channel 8. Taking the second part of the brush 1 being parallel to the second part of the buffer baffle 2 as an example, the length of the second part of the brush 1 is longer than the length of the second part of the buffer baffle 2 in the direction of extension towards the through channel 8. The fact that the brush 1 contacts the through channel 8 first makes the gap between the through channel 8 and the vehicle body 7 more completely blocked, thereby improving safety performance.
[0057] Of course, the second part of the brush 1 and the second part of the buffer baffle 2 may not be arranged in parallel.
[0058] This invention also provides a rail vehicle, including the brush structure described above. Because this solution employs the aforementioned brush structure, it possesses corresponding beneficial effects, as detailed in the preceding description, which will not be repeated here.
[0059] In order to quickly assemble this brush structure with the vehicle body 7, such as Figure 3 As shown, the mounting plate 33 of the bracket 3 can be connected to the vehicle body end wall 71 and the interior structure 72 using the second fastener. The interior structure belongs to the interior system and is part of the partition structure of the interior system. Its function is to shield the end wall vehicle body structure.
