[0002] Rail vehicles are vehicles that run on specific tracks and are used to transport people or goods. Rail vehicles used to transport people generally have suspension components necessary for work, such as luggage racks, bed boards, and seats, installed inside the car body. However, these suspension components are generally fixed to the car body with metal and screws. During the use of rail vehicles to transport people, the vibration of the car body will be transmitted to the wall panels through the metal seats, which will generate a lot of radiated noise and affect passenger comfort.

[0003] In conclusion, how to reduce the radiated noise of rail vehicles is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0039] This application provides a mounting structure for a suspension component, used to mount a suspension component 6 to a vehicle body 5. The mounting structure for the suspension component includes a fixing member 1, a connecting member 2, and an elastic connecting part 3. The fixing member 1 is used to connect to the vehicle body 5. The connecting member 2 has a connecting part for connecting to the suspension component 6 by means of a threaded fastener 7. The fixing member 1 is elastically connected to the connecting member 2 by means of the elastic connecting part 3, and the elastic connecting part 3 can absorb the vibration of the connecting member 2.

[0040] refer to Figures 1 to 3 As explained, the mounting structure for the suspension component is equipped with a fastener 1 so that the mounting structure for the suspension component can be mounted on the vehicle body 5, and is equipped with a connector 2. The connector 2 has a connecting part on its right side away from the connector 2, so that the suspension component 6 can abut against the right support surface of the connector 2. After the threaded fastener 7 is assembled in place, the suspension component 6 can be mounted on the vehicle body 5 through the mounting structure for the suspension component.

[0041] It should be noted that there are no restrictions on the type of connecting part, as long as it can meet the assembly requirements of connecting part 2 and suspension part 6.

[0042] In some embodiments, please refer to Figure 1 and Figure 2 The connecting part is a threaded hole, and the threaded fastener 7 is a screw. By passing the screw through the part to be connected 2 and screwing it into the connecting part, the connection between the part to be connected 2 and the connecting part 2 can be achieved.

[0043] In some embodiments, the connecting part is a stud and the threaded fastener 7 is a nut. After the connecting part passes through the part to be connected 2, the connecting nut that is threaded at the head end of the connecting part can realize the connection between the part to be connected 2 and the connecting part 2.

[0044] In some embodiments, the connecting part is a groove, preferably, the connecting member 2 is a groove profile; the threaded fastener 7 is a T-bolt or a square nut, etc. When the threaded fastener 7 is a T-bolt, the tail end of the threaded fastener 7 is slid into the connecting part, and the member to be connected 2 is placed in place. At this time, the threaded fastener 7 passes through the member to be connected 2, and then the connecting nut with the threaded end of the threaded fastener 7 is threaded to achieve the connection between the member to be connected 2 and the connecting member 2; when the threaded fastener 7 is a nut, the tail end of the threaded fastener 7 is slid into the connecting part, the member to be connected 2 is placed in place, and then the threaded rod passes through the member to be connected 2 and extends into the groove of the connecting part to achieve the connection between the member to be connected 2 and the connecting member 2.

[0045] It should also be noted that the aforementioned connecting component 2 refers not only to the aforementioned suspension component 6, but also to the transition structure that enables the connection between the suspension component 6 and the connecting component 2.

[0046] The beneficial effects are that the connector 2 is elastically connected to the fixing part 1 through the elastic connecting part 3. The elastic connecting part 3 can be a spring or an expandable and contractible rubber structure, etc. When in use, the vibration of the suspension component 6 is transmitted to the connector 2 and absorbed by the elastic connecting part 3 between the connector 2 and the fixing part 1. Thus, the installation structure of the suspension component provides installation strength while reducing vibration transmission, thereby effectively improving the cross-sectional sound insulation of the side wall and improving the comfort inside the vehicle. Moreover, since the connector 2 is equipped with a connecting part, the installation of the suspension component 6 does not require drilling.

The mounting groove can be a rectangular groove or a T-shaped groove, etc. An elastic connection part 3 is filled in the mounting groove. The elastic connection part 3 can be filled with rubber or polyurethane filler, etc. The left side structure of connector 2 is embedded inside the elastic connection part 3, and the elastic connection part 3 is tightly fitted with fastener 1 and connector 2, for example, by foaming, bonding or plugging, etc. The left side structure of connector 2 is embedded in the middle position of elastic connection part 3. That is, the side of connector 2 along the first direction, the side along the second direction and the side along the third direction all have part of the elastic connection part 3 structure, which can realize the vibration reduction of the suspension component 6 with full degrees of freedom. With this setting, while meeting the requirements of reducing vibration transmission and installation strength, the structure is simple and the manufacturing difficulty is low. Moreover, the installation structure of this suspension component can be used directly as a standard module, or a transition structure can be added to meet the different installation requirements of suspension component 6.

[0049] Of course, the elastic connection structure between the connector 2 and the fixing member 1 is not limited to the above-mentioned elastic connection part 3. For example, a first spring, a second spring and a third spring are provided between the connector 2 and the fixing member 1. The first spring extends along a first direction, and one end of the first spring is connected to one side of the connector 2 along the first direction, and the other end is connected to the fixing member 1. The second spring extends along a second direction, and one end of the second spring is connected to one side of the connector 2 along the second direction, and the other end is connected to the fixing member 1. The third spring extends along a third direction, and one end of the third spring is connected to one side of the connector 2 along the third direction, and the other end is connected to the fixing member 1.

[0052] refer to Figure 1 As can be seen, the two ends of the fastener 1 along its own length are mounting feet 12, and the middle position along its own length is the main body connecting part 11.

[0053] To meet the requirement that the mounting structure of this suspension component be mounted on the vehicle body 5, the mounting foot 12 can be an L-shaped plate or an attachment. Figure 3The plate structure shown has mounting holes on the mounting feet 12. The second fastener 8 inserted into the mounting holes of the two mounting feet 12 can be used to install the mounting structure of the suspension component.

[0054] To meet the requirements for the installation of the elastic connection part 3 in the mounting structure of the suspension component, the main connection part 11 is a C-shaped material, and the inner cavity of the C-shaped material is the aforementioned mounting groove.

[0055] It should be noted that the main connecting part 11 of the fastener 1 is not limited to the C-shaped material of the above embodiment, but can also be a T-shaped material or a flat plate, as long as it meets the installation requirements of the suspension component 6.

[0056] Based on the above embodiment, the main body connecting part 11 has a blocking protrusion 13 on the inner side of both side walls along its own width direction.

The blocking protrusions 13 can be arched protrusions or rectangular protrusions, etc., to reduce the possibility of the elastic connecting part 3 coming out of the mounting groove.

[0058] Based on the above embodiment, the connector 2 is an H-shaped material; the length direction of the connector 2 is parallel to the fixing member 1, and the first end of the connector 2 along its own height direction is embedded in the elastic connection part 3 in a T-shaped structure.

[0059] refer to Figure 2 and Figure 3 As can be seen, the height direction of the connector 2 mentioned above refers to the horizontal direction shown in the figure, that is, the direction of the vertical line connecting the two opposite flat plate structures of the connector 2.

[0060] The left side of the connector 2 is laid down and a T-shaped structure is embedded in the elastic connection part 3, while the right side of the connector 2 extends vertically and is located outside the right side of the elastic connection part 3 and abuts against the right side of the elastic connection part 3, so as to restrict the position of the elastic connection part 3 and facilitate the transmission of vibration from the suspension component 6 to the elastic connection part 3 through the connector 2.

[0061] Correspondingly, refer to Figure 2 As can be seen, the connecting part is a threaded hole, which is located in the middle of the connecting part 2 along its own width direction, and the insertion interface of the connecting part is located on the right support surface of the connecting part 2 away from the fixing part 1.

[0062] It should be noted that the connector 2 is not limited to the H-shaped material in the above embodiment, but can also be a T-shaped material, a C-shaped material, or a cylinder, as long as it meets the installation requirements of the suspension component 6.

[0063] Based on the above embodiments, the elastic connecting part 3 is a rubber filler, and the elastic connecting part 3 is vulcanized and connected to the connector 2 and the fixing part 1.

[0064] Based on the above embodiment, the elastic connection part 3 has a stiffness adjustment hole 31, which extends along the length direction of the fixing member 1.

[0065] A stiffness adjustment hole 31 is provided inside the elastic connection part 3. The stiffness adjustment hole 31 extends parallel to the length direction of the fixing member 1 and is a through hole that penetrates the elastic connection part 3. The stiffness adjustment hole 31 can be a channel with an elliptical or rhomboid cross-sectional shape, etc., for adjusting stiffness.

[0066] It should be noted that the number and arrangement of the stiffness adjustment holes 31 are not limited, as long as the stiffness adjustment requirements are met. For example, refer to... Figure 2 and Figure 3 As explained, the connecting plate connecting the two opposite sidewalls in the fastener 1 has a stiffness adjustment hole 31 between it and the fastener 2, that is, the part of the elastic connecting part 3 located on the side of the fastener 2 along the first direction has a stiffness adjustment hole 31; and / or, the sidewall in the fastener 1 has a stiffness adjustment hole 31 between it and the fastener 2, that is, the part of the elastic connecting part 3 located on the side of the fastener 2 along the second direction has a stiffness adjustment hole 31.

[0067] Based on the above embodiment, the connector 2 can be connected to the suspension component 6 via the transition member 4; the first end of the transition member 4 has a mounting through hole for inserting a threaded fastener 7; the second end of the transition member 4 is used to connect to the suspension component 6.

[0068] refer to Figure 5 As can be seen, the mounting structure of the suspension component is also equipped with a transition piece 4. The transition piece 4 can be a flat plate or a bent plate, etc. The left end of the transition piece 4 has a through hole for inserting a threaded fastener 7 to fix the transition piece 4 to the right side of the connector 2.

[0069] In use, the mounting through hole of the transition piece 4 is aligned with the opening of the connecting part of the connector 2 to meet the installation requirements of the threaded fastener 7, thus enabling the assembly of the transition piece 4 and the connector 2. In use, the right end of the transition piece 4 is fixedly connected to the suspension component 6 by means of fasteners or welding, and the assembly of the transition piece 4 and the connector 2 is achieved by means of threaded fastener 7, thus enabling the suspension component 6 to be mounted on the vehicle body 5 by the mounting structure of the suspension component.

[0070] Of course, the transition piece 4 and the connector 2 are not limited to the type of post-assembly. They can be two parts of the structure of the transition connector 2, that is, the transition connector 2 has the connector 2 and the transition piece 4. The part of the structure of the transition connector 2 is the connector 2, and the remaining structure is the transition piece 4.

[0071] It should also be noted that when the connector 2 and the transition piece 4 are two separate structures that need to be assembled, the assembly sequence of the suspension component using the mounting structure is not restricted. For example, in some embodiments, the connector 2 and the fixing piece 1 are first connected to the elastic connecting part 3 through vulcanization treatment, and then the transition piece 4 is installed on the connector 2; or, in some embodiments, the transition piece 4 is first installed on the connector 2, and then vulcanized integrally with the elastic connecting part 3 and the mounting base.
