[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] The embodiments of the present application provide a berth hinge mechanism, berth structure and vehicle with improved assembly performance, which can solve the problems in the related art of complex assembly of the berth hinge mechanism and poor assembly performance due to insufficient berth installation space.

[0035] See also Figures 1 to 4 As shown, the first aspect of the embodiment of the present application provides a berth hinge mechanism with improved assembly performance, comprising:

[0036] The fixing assembly comprises a U-shaped seat 3 arranged vertically and a rotating shaft 2 connected laterally to the U-shaped seat 3;

[0037] A rotating bracket 8, on which a hanging groove with a downward opening for the rotating shaft 2 to enter or escape is provided;

[0038] The elastic limiting bracket 6 includes a fixed section connected to the rotating bracket 8 and a free section extending toward the rotating shaft 2 . The free section abuts against the rotating shaft 2 and limits the rotating shaft 2 in the hanging groove.

[0039] The berth hinge mechanism with improved assembly performance in the embodiment of the present application includes a fixed component, a rotating bracket 8 and an elastic limiting bracket 6, the fixed component includes a vertically arranged U-shaped seat 3 and a rotating shaft 2 laterally connected to the U-shaped seat 3, the rotating bracket 8 is provided with a hanging groove with an opening facing downward for the rotating shaft 2 to enter or detach, the elastic limiting bracket 6 includes a fixed section connected to the rotating bracket 8 and a free section extending in the direction of the rotating shaft 2, the free section abuts against the rotating shaft 2 and confines the rotating shaft 2 in the hanging groove. During specific use, the U-shaped seat 3 equipped with the rotating shaft 2 is vertically fixed on the body sheet metal wall of the carriage, and holes can be made on the U-shaped seat 3 and the body sheet metal and fixed by bolt locking. Then the rotating bracket 8 equipped with an elastic limiting bracket 6 is fixed to the side of the berth board, and holes can be made on the rotating bracket 8 and the berth board and fixed by bolt locking. Then, the rotating bracket 8 is hung on the rotating shaft 2 on the U-shaped seat 3 by moving the berth, and the rotating shaft 2 enters the hanging groove on the rotating bracket 8. The free section of the elastic limiting bracket 6 abuts against the rotating shaft 2 and confines the rotating shaft 2 in the hanging groove, ensuring that the rotating bracket 8 can rotate around the rotating shaft 2 while the rotating shaft 2 will not separate from the rotating bracket 8, thereby completing the installation of the berth.

[0040] It should be noted that at least two rotating brackets 8 are installed on the side of the berth board, and the same number of U-shaped seats 3 as the rotating brackets 8 are installed on the sheet metal wall of the vehicle body. The central axis of the rotating shaft 2 of the multiple U-shaped seats 3 coincides, ensuring that it can be hung in place. After being hung in place, the berth board will not shake, and the overall installation is convenient. At the same time, the installation space required for hanging is small and is not limited by the installation space. Compared with conventional hinges, it does not require personnel to drag upwards and then assemble the hinge assembly connected to the body sheet metal. The corresponding components can be installed on the berth and the body sheet metal respectively, and then the hanging is performed to complete the hinge installation, ensuring the reliability of the hinge mechanism while avoiding shaking, and the overall operation is convenient. It should also be noted that when hanging, the berth can be hung by manually holding the berth or by clamping the berth by a robot. The overall online assembly of the robot can further improve the assemblability. Specifically, the use of a hanging method improves the convenience of manipulator assembly. By setting a specified moving route for the manipulator, the hanging method makes it easier to realize berth assembly, which improves the assembly performance and the efficiency of berth installation.

[0041] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a berth hinge mechanism with improved assembly performance, wherein the elastic limit bracket 6 of the berth hinge mechanism with improved assembly performance is a spring steel sheet, and the free section includes a support section located below the rotating shaft 2 and an arc section that is in contact with the rotating shaft 2 and extends away from the U-shaped seat 3.

[0042] The elastic limiting bracket 6 of the berth hinge mechanism for improving assembly performance in the embodiment of the present application is a spring steel sheet, and the free section includes a supporting section located below the rotating shaft 2 and an arc section that is in contact with the rotating shaft 2 and extends in a direction away from the U-shaped seat 3. During specific use, a U-shaped seat 3 connected to the rotating shaft 2 is installed on the side wall of the berth board, and a rotating bracket 8 is installed on the sheet metal wall of the vehicle body of the carriage. The fixed end of the elastic limiting bracket 6 is fixed to the elastic limiting bracket 6, and the fixed end of the elastic limiting bracket 6 can be fixed to the rotating bracket 8 by bolts or welding. When the mobile berth is hung, the rotating bracket 8 approaches the rotating shaft 2, squeezing the supporting section of the elastic limiting bracket 6. The supporting section of the elastic limiting bracket 6 is swung and deformed with the fixed end as the fulcrum when viewed from above. The rotating shaft 2 slides upward along the supporting section of the elastic limiting bracket 6 and enters the rotating bracket 8 from bottom to top. In the hanging groove, after the rotating shaft 2 enters the hanging groove, it is separated from the supporting section of the elastic limiting bracket 6. The supporting section of the elastic limiting bracket 6 recovers its deformation and resets, so that the arc section of the elastic limiting bracket 6 fits and abuts against the cylindrical surface of the rotating shaft 2. The arc section of the elastic limiting bracket 6 limits the rotating shaft 2 in the hanging groove on the rotating bracket 8, and does not affect the rotation of the rotating shaft 2 relative to the arc section. When hanging, the elastic limiting bracket 6 automatically avoids, and after the rotating shaft 2 is installed in place, the elastic limiting bracket 6 automatically resets to limit the separation of the rotating shaft 2, thereby improving the assembly processability, and the overall structure is simple and easy to promote and use. It should be noted that the arc section of the elastic limiting bracket 6 is used to limit the separation of the rotating shaft 2 from the opening of the hanging groove. Those skilled in the art can adaptively adjust the size of the arc section according to the specific use situation and test conditions.

[0043] In some alternative embodiments: See Figures 1 to 4 As shown, the embodiment of the present application provides a berth hinge mechanism with improved assembly performance, and the berth hinge mechanism with improved assembly performance also includes a limit shaft 5 connected to a rotating bracket 8, the support section extends outward to form an extension section, and the limit shaft 5 is clamped in a groove formed by the extension section and the elastic limit bracket 6;

[0044] It also includes a retaining clamp 4 for fixing the support section and the extension section. The retaining clamp 4 is hinged on the rotating bracket 8 through a limiting shaft 5.

[0045] The limiting shaft 5 connected to the rotating bracket 8 of the berth hinge mechanism for improving assembly performance in the embodiment of the present application, at the same time, the support section extends outward to form an extension section, the limiting shaft 5 is clamped in the groove formed by the extension section and the elastic limiting bracket 6, and a retaining clip 4 for fixing the support section and the extension section is also installed, and the retaining clip 4 is hinged on the rotating bracket 8 through the limiting shaft 5. When in use, the retaining clip 4 clamps and fixes the support section and the extension section of the elastic limiting bracket 6 together, the limiting shaft 5 passes through the mounting hole reserved on the retaining clip 4, and the retaining clip 4 is hinged on the rotating bracket 8 through the limiting shaft 5. Specifically, the retaining clip 4 can rotate on the limiting shaft 5, and the limiting shaft 5 is riveted or welded in the mounting hole reserved on the rotating bracket 8, or the retaining clip 4 is riveted or welded on the limiting shaft 5, and the limiting shaft 5 is rotatably connected in the mounting hole reserved on the rotating bracket 8, and at the same time, the fixed section of the elastic limiting bracket 6 is fixed. When the berth equipped with the U-shaped seat 3 is hung, the U-shaped seat 3 drives the rotating shaft 2 close to the rotating bracket 8. The bracket 8 is rotated to make the rotating shaft 2 squeeze the retaining clip 4 at the position above the limiting shaft 5, so that the retaining clip 4 restricted by the limiting shaft 5 is deflected, and at the same time, the retaining clip 4 drives the supporting section of the elastic limiting bracket 6 to deflect, and the supporting section of the elastic limiting bracket 6 is bent and deformed, and the supporting section of the elastic limiting bracket 6 drives the arc section to move, and the arc section of the elastic limiting bracket 6 makes way for the opening position of the hanging groove, and the rotating shaft 2 slides along the surface of the retaining clip 4, and then enters the hanging groove from the opening position of the hanging groove, and the supporting section of the elastic limiting bracket 6 recovers its deformation and drives the retaining clip 4 to reset, so that the arc section of the elastic limiting bracket 6 is against the limiting rotating shaft 2.

[0046] It should be noted that the support section and the extension section of the elastic limiting bracket 6 cooperate to provide a sufficient clamping surface for the retaining clamp 4, avoiding the instability caused by directly clamping the side of the fixed supporting section. The clamping surface formed by the side of the extension section cooperates with the side of the supporting section to ensure the clamping stability. At the same time, the Y-mouth formed by the support section and the extension section of the elastic limiting bracket 6 is convenient for positioning on the limiting shaft 5, ensuring that the retaining clamp 4 clamps the support section of the fixed elastic limiting bracket 6 accurately, reducing assembly errors and ensuring assembly accuracy.

[0047] It should be noted that the direction of the extension section of the elastic limiting bracket 6 can be adjusted according to actual conditions. When the direction of the extension section of the elastic limiting bracket 6 is downward, the Y-mouth formed by the support section and the extension section of the elastic limiting bracket 6 is convenient for being clamped on the limiting shaft 5 for positioning, thereby supporting the arc section of the elastic limiting bracket 6 and ensuring that the arc section of the elastic limiting bracket 6 can stably limit the rotating shaft 2; when the direction of the extension section of the elastic limiting bracket 6 is upward, the Y-mouth formed by the support section and the extension section of the elastic limiting bracket 6 is convenient for being clamped on the limiting shaft 5 for positioning. After the retaining clip 4 clamps and fixes the support section and the extension section of the elastic limiting bracket 6, the Y-mouth formed by the support section and the extension section of the elastic limiting bracket 6 pulls the arc section of the elastic limiting bracket 6 upward to prevent the elastic limiting bracket 6 from detaching from the rotating bracket 8.

[0048] It should be noted that the present application does not make specific requirements or special limitations on the structural features such as the size, shape and material of the retaining clip 4. The function of the retaining clip 4 in the present application is to clamp and support the supporting section of the elastic limiting bracket 6 to prevent the elastic limiting bracket 6 from detaching from the rotating bracket 8, and at the same time provide an extrusion surface for the rotating shaft 2 to prevent the rotating shaft 2 from directly rubbing the supporting section of the elastic limiting bracket 6. Therefore, it can be understood that other retaining clips 4 that can achieve such functions can be used in the present application, and technical personnel in this field can adaptively adjust the size, shape and material of the retaining clip 4 according to the usage scenario and test conditions.

[0049] It should be noted that, during the rotation process, the U-shaped seat 3 will not squeeze the retaining clip 4 , but will abut against the limiting shaft 5 , thereby limiting the rotation range of the U-shaped seat 3 .

[0050] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a berth hinge mechanism with improved assembly performance, and the berth hinge mechanism with improved assembly performance also includes a reinforcing plate 7 arranged on a rotating bracket 8, a clamping hole is opened on the reinforcing plate 7, and a fixed section is clamped in the clamping hole.

[0051] The berth hinge mechanism for improving assembly performance of the embodiment of the present application also includes a reinforcing plate 7 arranged on the rotating bracket 8, and a clamping hole is provided on the reinforcing plate 7, and the fixed section is clamped in the clamping hole. It should be noted that the reinforcing plate 7 is fixed on the rotating bracket 8, specifically fixed to the rotating bracket 8 by threaded connection, that is, the bolt passes through the reserved mounting hole on the rotating bracket 8 and the reserved mounting hole on the reinforcing plate 7 at the same time. The reinforcing plate 7 and the rotating bracket 8 cooperate to ensure the connection strength with the sheet metal wall of the carriage body and avoid weak connection. At the same time, a clamping hole is provided on the reinforcing plate 7 for inserting the fixed section of the elastic limiting bracket 6, so that the fixed section of the elastic limiting bracket 6 is easy to install. In conjunction with the retaining clip 4 and the limiting shaft 5, the fixed section of the elastic limiting bracket 6 only needs to be inserted into the clamp on the reinforcing plate 7 to position the fixed section of the elastic limiting bracket 6.

[0052] It should be noted that the present application does not make specific requirements or special limitations on the structural features such as size, shape and material of the reinforcing plate 7. The function of the reinforcing plate 7 in the present application is to allow the fixed section of the elastic limiting bracket 6 to be inserted into the slot on the reinforcing plate 7, thereby positioning the fixed section of the elastic limiting bracket 6. Therefore, it can be understood that other reinforcing plates 7 that can achieve such functions can be used in the present application, and technical personnel in this field can adaptively adjust the size, shape and material of the reinforcing plate 7 according to the usage scenario and test conditions.

[0053] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a berth hinge mechanism with improved assembly performance, wherein a rotating bracket 8 of the berth hinge mechanism with improved assembly performance includes a fixed plate connected to a reinforcing plate 7 and two hooks connected to a rotating shaft 2 and forming a hanging groove, and the two hooks are located on the left and right sides of an elastic limiting bracket 6.

[0054] The rotating bracket 8 of the berth hinge mechanism for improving assembly performance of the embodiment of the present application includes a fixed plate connected to the reinforcing plate 7 and two hooks connected to the rotating shaft 2 and forming a hanging groove, and the two hooks are located on the left and right sides of the elastic limit bracket 6. When in use, the fixed plate is used to fit the body sheet metal bolts of the carriage and fixedly installed, and the rotating shaft 2 on the U-shaped seat 3 enters into the hook, and when rotating, the hook rotates around the rotating shaft 2. It should be noted that the positions of the two hooks can be located on both sides of the U-shaped seat 3 and contact the outer surface of the U-shaped seat 3, limiting the lateral movement of the U-shaped seat 3 along the rotating bracket 8. At the same time, the positions of the two hooks can also be located on the inner side of the U-shaped seat 3 and contact the outer surface of the U-shaped seat 3, which can also play a role in limiting the lateral movement of the U-shaped seat 3 along the rotating bracket 8. At the same time, the number of hooks can also be increased to ensure that the weight of the berth can be shared when hanging.

[0055] In some alternative embodiments: See Figures 1 to 4As shown, the embodiment of the present application provides a berth hinge mechanism with improved assembly performance, and two side panels extending to both ends of the rotating shaft 2 are arranged on both sides of the rotating bracket 8 of the berth hinge mechanism with improved assembly performance. When used specifically, the limit shaft 5 can be installed on the two side panels, and the side panels can also close one side of the hook to prevent the rotating shaft 2 from axially moving out of the hook.

[0056] The swivel bracket 8 of the berth hinge mechanism for improving assembly performance in the embodiment of the present application is provided with two side plates extending to the two ends of the swivel shaft 2 on both sides.

[0057] In some alternative embodiments: See Figures 1 to 3 As shown, an embodiment of the present application provides a berth hinge mechanism with improved assemblability, wherein the top of the fixed plate of the berth hinge mechanism with improved assemblability is provided with an operating groove for exposing the free section.

[0058] The top of the fixed plate of the berth hinge mechanism for improving assembly performance in the embodiment of the present application is provided with an operating slot for exposing the free section. When in use, the operating slot exposes the position of the free section of the elastic limit bracket 6, providing an operating space for moving the free section of the elastic limit bracket 6, and at the same time, when hanging, providing the free section of the elastic limit bracket 6 with a space to make way after deformation. When the berth needs to be removed from the carriage, the free section of the elastic limit bracket 6, that is, the arc section abutting against the rotating shaft 2, is moved to separate the arc section of the elastic limit bracket 6 from the rotating shaft 2, and the arc section drives the support section and the retaining clip 4 to deflect, thereby making way for the opening position of the hanging slot, and the berth is moved upward, which can drive the rotating bracket 8 to separate upward from the rotating shaft 2, thereby achieving the purpose of convenient disassembly.

[0059] In some alternative embodiments: See Figures 1 to 4 As shown, an embodiment of the present application provides a berth hinge mechanism with improved assembly performance, wherein both ends of the rotating shaft 2 of the berth hinge mechanism with improved assembly performance are provided with shaft sleeves 1 for fixing the rotating shaft 2 on a U-shaped seat 3, and the shaft sleeves 1 are adapted to the hanging grooves.

[0060] Both ends of the rotating shaft 2 of the berth hinge mechanism for improving assembly performance in the embodiment of the present application are provided with a sleeve 1 for fixing the rotating shaft 2 on the U-shaped seat 3, and the sleeve 1 is adapted to the hanging groove. It should be noted that, as an option, the sleeve 1 is made of plastic material, such as nylon or polyformaldehyde material. Nylon or polyformaldehyde material has good self-lubricating properties, and thus replaces the combination of grease and metal shaft. At the same time, the hardness of nylon or polyformaldehyde material is less than that of the rotating bracket 8 made of metal material, and the friction noise during rotation can be reduced during contact friction, thereby improving the user experience. When used specifically, the rotating shaft 2 can be fixed on the U-shaped seat 3 by riveting or welding, and the two sleeves 1 are respectively sleeved and fixed on the two ends of the rotating shaft 2. When hanging, the two sleeves 1 enter the inner side of the two hooks accordingly.

[0061] It should be noted that the sleeve 1 and the rotating shaft 2 can be installed by means of an interference fit connection. One end of the sleeve 1 can be sealed, and the other end of the sleeve 1 can be flanging. Specifically, the other end of the sleeve 1 extends to the outer periphery with an annular flange. In specific use, the sleeve 1 is sleeved on the end of the rotating shaft 2, and the sealed end of the sleeve 1 contacts the side plate on the rotating bracket 8 to prevent the rotating shaft 2 from rubbing against the side plate. At the same time, the annular flange of the sleeve 1 separates the U-shaped seat 3 and the hook to prevent friction between the U-shaped seat 3 and the hook. The self-lubricating property of the plastic material of the sleeve 1 ensures a good rotation experience without noise or abnormal sound.

[0062] See also Figures 1 to 4 As shown, the second aspect of the embodiment of the present application provides a berth structure, comprising:

[0063] Body sheet metal;

[0064] Sleeper;

[0065] A berth hinge mechanism with improved assembly performance according to any of the above embodiments, wherein the U-shaped seat 3 is connected to the side wall of the vehicle body sheet metal, and the rotating bracket 8 is connected to the side of the berth.

[0066] A berth hinge mechanism for improving assembly performance of any of the above embodiments is arranged between the body sheet metal and the berth of the berth structure of the embodiment of the present application. The specific use process is that the U-shaped seat 3 is installed on the side wall of the body sheet metal, and the rotating bracket 8 is installed on the side of the berth. The rotating shaft 2 and the sleeve 1 are installed in advance on the U-shaped seat 3, and the reinforcing plate 7, the limiting shaft 5, the elastic limiting bracket 6 and the retaining clamp 4 are installed in advance on the rotating bracket 8. When the manipulator is used to clamp and move the berth for hanging, the rotating bracket 8 approaches the rotating shaft 2, squeezes the supporting section of the elastic limiting bracket 6, and the supporting section of the elastic limiting bracket 6 is swung and deformed with the fixed end as the fulcrum. The rotating shaft 2 slides upward along the supporting section of the elastic limiting bracket 6 and enters the hanging groove on the rotating bracket 8 from bottom to top. After the rotating shaft 2 enters the hanging groove, it is separated from the supporting section of the elastic limiting bracket 6, and the supporting section of the elastic limiting bracket 6 recovers the deformation and resets, so that the arc section of the elastic limiting bracket 6 fits and abuts against the cylindrical surface of the rotating shaft 2, that is, the installation is completed. It should be noted that the arc section of the elastic limiting bracket 6 limits the rotating shaft 2 in the hanging groove on the rotating bracket 8, and does not affect the rotation of the rotating shaft 2 relative to the arc section, so that the elastic limiting bracket 6 automatically avoids when hanging, and the elastic limiting bracket 6 automatically resets after the rotating shaft 2 is installed in place to limit the detachment of the rotating shaft 2, thereby optimizing the assembly processability of the berth installation and improving the berth assembly efficiency.

[0067] It should be noted that the assembly process of the berth installation can form a modular installation, thereby improving the assembly efficiency of the berth. Specifically, the U-shaped seat 3, the rotating shaft 2 and the sleeve 1 are combined into a fixed end module assembly, the fixed end module assembly is installed on the body sheet metal, the retaining clamp 4, the limit shaft 5, the elastic limit bracket 6, the reinforcing plate 7 and the rotating bracket 8 are combined into a rotating end module assembly, the rotating end module assembly is installed on the berth, and the fixed end module assembly and the rotating end module assembly are finally assembled by hanging, so that the berth connected to the rotating end module assembly can be easily assembled to the fixed end module assembly, thereby improving the assembly process; after assembly, the elastic limit bracket contacts the rotating shaft 2 through its own elasticity, ensuring the reliability of the hinge mechanism while avoiding shaking. At the same time, the berth can be changed from manual assembly to overall online assembly of the manipulator. In order to improve the convenience of manipulator assembly, a hanging method is adopted. By setting a specified route for the manipulator, the berth assembly is easier to achieve through the hanging method, further improving the assembly efficiency.

[0068] See also Figures 1 to 4 As shown, a third aspect of the embodiment of the present application provides a vehicle, including:

[0070] Sleeper;

[0071] A berth structure of the above embodiment.

[0072] The vehicle of the embodiment of the present application uses the berth structure of the above-mentioned embodiment, which improves the assembly processability of vehicle components and at the same time improves the assembly efficiency of the vehicle, making it easy to promote and use.

[0073] In the description of the present application, it should be noted that the terms "upper", "lower", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.
