Description

Technical Field

[0001] This invention relates to the field of vehicle interior parts technology, and in particular to a vehicle sleeper berth tilting structure and a vehicle sleeper berth assembly. Background Technology

[0002] With the technological advancements in vehicle interior components and the increasing demands of users, creating a complete living space through structural concealment and spatial transformation has become an important aspect of vehicle design. Conventional vehicle interior component designs include techniques such as large-travel sliding seats and the inclusion of folding sleeper berths to adjust and change the interior space, expanding its functionality for dining, entertainment, or rest. The changing usage and folding states of the sleeper berth can significantly alter the interior space. Due to the special function of the sleeper berth, the design of the folding structure connecting the sleeper berth to the vehicle interior must simultaneously consider stability and space occupancy.

[0003] Currently, there are two common types of sleeper berth flipping methods: one is the integrated frame flipping type, which has a larger flipping angle of about 45° and requires the cooperation of hinges and gas struts; the other is the non-integrated frame flipping type, which has a flipping angle of about 90° and a simple connection structure between the sleeper berth and the interior of the vehicle.

[0004] However, among the aforementioned sleeper berth flipping methods, the integrated frame flipping method requires a large layout space and a large number of parts, while the non-integrated frame flipping structure, although simple in structure, requires the sleeper berth to be supported by outriggers after flipping, which is laborious and inconvenient to operate. Summary of the Invention

[0005] Therefore, it is necessary to provide a vehicle sleeper berth tilting structure and vehicle sleeper berth assembly that occupy little space, have a simple connection structure, and are easy to operate, in order to address the above-mentioned technical problems.

[0009] A flip-link structure connects the flip-structure fixing component and the berth fixing component, and is used to realize the angle change between the berth fixing component and the flip-structure fixing component;

[0010] When the berth body is flipped into the use state, the flipping linkage structure achieves self-locking, which serves to support the berth body.

[0011] In one embodiment, after the berth body is flipped into the use state, the angle between the berth fixing member and the flipping structure fixing member changes to 90 degrees.

[0014] One end of the inner ring deformable link assembly is hinged to the berth fixing component, and the other end of the inner ring deformable link assembly is hinged to the flipping structure fixing component.

[0015] The outer ring deformable link assembly is coupled and linked with the inner ring deformable link assembly. During the flipping process of the berth body, the deformation trajectory of the outer ring deformable link assembly is located outside the deformation trajectory of the inner ring deformable link assembly.

[0016] In one embodiment, the outer ring deformable link assembly includes a first outer ring link and a second outer ring link;

[0017] One end of the first outer ring connecting rod is hinged to the flipping structure fixing member, the other end of the first outer ring connecting rod is hinged to one end of the second outer ring connecting rod, and the other end of the second outer ring connecting rod is hinged to the berth fixing member;

[0018] The middle part of the first outer ring connecting rod is coupled to the inner ring deformable connecting rod assembly.

[0019] In one embodiment, the inner ring deformable link assembly includes a first inner ring link and a second inner ring link;

[0021] In one embodiment, there are two sets of outer ring deformable link assemblies and inner ring deformable link assemblies, which are parallel to each other and spaced apart.

[0022] In one embodiment, a friction element is provided at the hinge of the inner ring deformable connecting rod assembly and the flipping structure fixing member to increase the friction force during the flipping process of the berth body.

[0023] In one embodiment, the friction element is provided at each hinge position of the outer ring deformable link assembly and the inner ring deformable link assembly.

[0024] Secondly, this application also provides a sleeper assembly for vehicles, including the sleeper tilting structure and sleeper body described in any of the above claims.

[0025] A pull-out table assembly is provided on the bottom plate of the sleeper body;

[0026] The pull-out table assembly includes a slide rail and a table body mounted on the base plate, and the table body is fixedly connected to the movable part of the slide rail.

[0027] The aforementioned vehicle sleeper berth tilting structure and vehicle sleeper berth assembly use a tilting linkage structure to connect the tilting structure fixing component that connects the internal structural components of the vehicle and the sleeper fixing component that connects the sleeper body. The dynamic changes in the tilting linkage structure itself enable the sleeper body to be tilted and supported, making the vehicle sleeper berth tilting structure space-saving, with a simple connection structure and convenient operation.

[0042] See Figure 1-Figure 3 , Figure 1-Figure 3 A vehicle sleeper berth flipping structure 2 according to an embodiment of the present invention is shown. The vehicle sleeper berth flipping structure 2 includes: a flipping structure fixing member 21, a sleeper berth fixing member 26, and a flipping linkage structure.

[0043] Continue reading Figure 1-Figure 3 The flipping structure fixing component 21 is used to fix and connect with the internal structural components of the vehicle; the sleeper fixing component 26 is used to fix and connect with the sleeper body 1; the flipping linkage structure connects the flipping structure fixing component 21 and the sleeper fixing component 26, and is used to realize the angle change between the sleeper fixing component 26 and the flipping structure fixing component 21; wherein, after the sleeper body 1 is flipped to the use state, the flipping linkage structure achieves self-locking and plays the role of supporting the sleeper body 1.

[0044] The aforementioned sleeper berth fixing component 26 is detachably and fixedly connected to the bottom plate 12 of the sleeper berth body 1. The entire sleeper berth body 1 is protected by a skin covering, making the sleeper berth body 1 aesthetically pleasing. The flipping structure fixing component 21 is fixedly connected to the internal structural components of the vehicle. The internal structural components of the vehicle can be the rear structure of the cab or other internal frame structures. When the sleeper berth body 1 is in use after being flipped over, as... Figure 1 as well as Figure 2 In the status view (a), the sleeper berth 1 is folded upwards and stored when not in use, as shown below. Figure 2 View b: During the transition between the use state and the storage state of the berth body 1, the dynamic changes of the flipping linkage structure itself occur. In the use state, the berth body 1 is supported from the bottom when it is lying flat, and in the storage state, the berth body 1 is supported from the bottom when it is standing upright.

[0045] In this embodiment, the vehicle sleeper berth flipping structure uses a flipping linkage structure to connect the flipping structure fixing member 21 that connects the internal structural components of the vehicle and the sleeper fixing member 26 that connects the sleeper body 1. The sleeper body 1 can be supported after flipping by the dynamic change of the flipping linkage structure itself, so that the vehicle sleeper berth flipping structure occupies little space, has a simple connection structure and is easy to operate.

[0046] Figure 2 A schematic diagram of a vehicle sleeper assembly according to an embodiment of the present invention is shown. In some embodiments, after the sleeper body 1 is flipped into the use state, the angle between the sleeper fixing member 26 and the flipping structure fixing member 21 changes by 90 degrees. In the use state, the sleeper body 1 is horizontal relative to the vehicle, and in the storage state, the sleeper body 1 is vertical relative to the vehicle and fits against the rear structure of the cab.

[0047] See Figures 3-6 , Figure 3 A schematic diagram of a vehicle sleeper berth tilting structure according to an embodiment of the present invention is shown. The tilting linkage structure includes an outer ring deformable linkage assembly and an inner ring deformable linkage assembly. One end of the outer ring deformable linkage assembly is hinged to the sleeper berth fixing member 26, and the other end of the outer ring deformable linkage assembly is hinged to the tilting structure fixing member 21. One end of the inner ring deformable linkage assembly is hinged to the sleeper berth fixing member 26, and the other end of the inner ring deformable linkage assembly is hinged to the tilting structure fixing member 21. The outer ring deformable linkage assembly and the inner ring deformable linkage assembly are coupled and linked.

[0048] Figure 5 This diagram shows a perspective view (in use) of the vehicle sleeper berth tilting structure of this embodiment. Figures 3 to 5 The flipping process has two initial and final states. During the flipping of the sleeper body 1, the deformation trajectory of the outer ring deformable link assembly is located outside the deformation trajectory of the inner ring deformable link assembly. During the coupling and linkage process between the outer ring deformable link assembly and the inner ring deformable link assembly of the flipping link structure, the overall shape and stress state of the two link assemblies change synchronously, realizing the deformation of the flipping link structure and the change of the shape and position of the supporting structure.

[0049] Continue reading Figures 3-6 The outer ring deformable link assembly includes a first outer ring link 22 and a second outer ring link 25; one end of the first outer ring link 22 is hinged to the flipping structure fixing member 21, the other end of the first outer ring link 22 is hinged to one end of the second outer ring link 25, and the other end of the second outer ring link 25 is hinged to the berth fixing member 26; the middle part of the first outer ring link 22 is coupled to the inner ring deformable link assembly.

[0050] Continue reading Figures 3-6 The inner ring deformable link assembly includes a first inner ring link 23 and a second inner ring link 24; one end of the first inner ring link 23 is hinged to the flipping structure fixing member 21, the other end of the first inner ring link 23 is hinged to the middle of the second inner ring link 24, one end of the second inner ring link 24 is hinged to the berth fixing member 26, and the other end of the second inner ring link 24 is hinged to the middle of the first outer ring link 22.

[0051] The two hinge positions on the flipping structure fixing member 21 are spaced apart, and the two hinge positions on the berth fixing member 26 are spaced apart, ensuring that the deformation trajectory of the outer ring deformable link assembly is located outside the deformation trajectory of the inner ring deformable link assembly.

[0052] See Figure 3 The first outer ring connecting rod 22 is a curved rod, comprising a first segment and a second segment. The included angle between the axes of the first segment and the second segment is an obtuse angle. The connection between the first segment and the second segment is hinged to the second inner ring connecting rod 24, which is located inside the obtuse angle. This makes the overall configuration of the outer ring deformable connecting rod assembly curved. The outer ring deformable connecting rod assembly has four hinge points, all located on the deformation trajectory of the outer ring deformable connecting rod assembly. The second outer ring connecting rod 25, the first inner ring connecting rod 23, and the second inner ring connecting rod 24 are all straight. The inner ring deformable connecting rod assembly has four hinge points, but three of them are located on the deformation trajectory of the inner ring deformable connecting rod assembly. The remaining hinge point enables the coupling and linkage between the outer ring deformable connecting rod assembly and the inner ring deformable connecting rod assembly. All of these hinge points are pin-type connections. The overall shape change of the outer ring deformable link assembly and the inner ring deformable link assembly is divided into two deformation areas: the first deformation area is located on the side of the sleeper berth fixing member 26, and the second deformation area is located on the side of the flipping structure fixing member 21.

[0053] When the sleeper berth body 1 is in the stowed state, such as Figure 3 As shown, the area of ​​the first deformation region is compressed, and the area of ​​the second deformation region is increased. Under the gravity of the berth body 1, the second inner ring connecting rod 24 transmits the force to the first inner ring connecting rod 23 and the first outer ring connecting rod 22, so that the first inner ring connecting rod 23 and the first outer ring connecting rod 22 have a tendency to rotate away from the berth body 1 around the hinge point with the flipping structure fixing member 21 and are limited, so that the berth flipping structure 2 plays the role of supporting the berth body 1 from the lower side.

[0054] During the flipping process of the sleeper body 1, the gravity of the sleeper body 1 acts on the second inner ring connecting rod 24 and the second outer ring connecting rod 25, causing the relative distance between them to change. The area of ​​the first deformation region increases, and the area of ​​the second deformation region decreases due to the coupling and linkage between the outer ring deformation connecting rod assembly and the inner ring deformation connecting rod assembly.

[0055] When the sleeper body 1 is in use, after the first inner ring connecting rod 23 reaches its limit position, the area of ​​the second deformation area cannot change, the shape of the first deformation area is fixed, and the posture of the sleeper body 1 is also fixed, so that the sleeper flipping structure 2 can support the sleeper body 1 lying flat from the bottom of the sleeper body 1.

[0056] The vehicle sleeper berth tilting structure 2 of this embodiment uses a six-link linkage structure composed of an outer ring deformable link assembly and an inner ring deformable link assembly to achieve stable and reliable tilting of the sleeper body 1, while saving layout and tilting space. Each link structure supports each other, and the state of the sleeper berth tilting structure 2 can be locked when the sleeper body 1 is in use, supporting the sleeper body 1 from below. When the sleeper body 1 is in the storage state, it is supported from the lower side of the sleeper body 1. The compact link structure achieves support in different states on one side of the sleeper body 1.

[0057] In one exemplary embodiment, such as Figures 5-6 As shown, there are two sets of rotating link structures: an outer ring deformable link assembly and an inner ring deformable link assembly, which are parallel to each other and spaced apart.

[0058] In this embodiment, the two outer ring deformable link assemblies are connected by a connecting plate 28, wherein there are two connecting plates 28. The two second outer ring links 25 are connected by a connecting plate 28, and the two first outer ring links 22 are connected by a connecting plate 28, thereby enhancing the strength and load-bearing capacity of the single flip link structure. The two second outer ring links 25 and the connecting plate 28 are integrally formed, and the two first outer ring links 22 and the connecting plate 28 are integrally formed.

[0059] In the previous exemplary embodiment, such as Figure 5 , Figure 6 As shown, multiple connecting rods are all sheet-like structures arranged in layers. The second outer ring connecting rod 25 is located on the innermost side and is on the same swing plane as the second inner ring connecting rod 24. The first inner ring connecting rod 23 is located outside the second inner ring connecting rod 24, and the first outer ring connecting rod 22 is located outside the first inner ring connecting rod 23. Figure 6 As shown, the maximum distance between the two first outer ring connecting rods 22 is distance a, the distance between the two hinged ear plates on the berth fixing member 26 is distance b, the distance between the two first inner ring connecting rods 23 is distance c, and the two second outer ring connecting rods 25 are located within the range of distance c. In this embodiment, each pair of connecting rods of the flipping connecting rod structure has a different nested cross section, realizing the flexible change of the relative position of each connecting rod during the flipping process.

[0060] In one exemplary embodiment, such as Figures 5-6 As shown, a friction element 27 is provided at the hinge point between the inner ring deformable connecting rod assembly and the flipping structure fixing member 21 to increase the friction force during the flipping process of the berth body 1. That is, a friction element 27 is provided at the hinge point between the first inner ring connecting rod 23 and the flipping structure fixing member 21, and the rotation of the first inner ring connecting rod 23 is restricted by friction to achieve locking in the folded state.

[0061] In an exemplary embodiment, the friction element 27 is made of nylon or other deformable, wear-resistant non-metallic material with a certain amount of elastic deformation. The friction element 27 is located between the pin and the pin hole at the hinge position and is a gasket in the form of a cylindrical surface contact. The two hinged links can be locked by friction.

[0062] In another embodiment, each hinge position of the outer ring deformable link assembly and the inner ring deformable link assembly is provided with a friction element 27. This creates a pin-hole fit and surface contact at each hinge point. The compression and clearance of each fit are adjusted by varying the thickness of the friction element 27, thus ensuring stable movement of the berth body 1 during tilting and providing a reliable locking force after the berth has tilted to 90°. In other words, by setting a friction and interlocking structure at the hinge points in the six-bar linkage structure, stability of the berth body 1 after tilting is achieved, freeing the user's hands and improving the convenience of loading and unloading items. The pins at each hinge point are tightly fitted with each link, forming a tilting mechanism capable of stable movement. The compression and fit of each link can be adjusted by adjusting the friction element 27. The operating force and locking force of the berth tilting structure 2 can be controlled and adjusted by varying the thickness of the friction element 27.

[0063] The vehicle sleeper berth flipping structure 2 of this embodiment, through the close cooperation of the linkage structure, can ensure the stability and reliability of the sleeper body 1 during the flipping process, without the need for auxiliary support structures such as gas struts, and can also lock the sleeper body 1 in the storage state.

[0064] In another embodiment, a limiting structure is provided in the internal structural components of the vehicle to further fix the berth body 1 in the storage state to the internal structural components of the vehicle.

[0065] In one exemplary embodiment, the present invention provides a vehicle sleeper assembly including a vehicle sleeper tilting structure 2 and a sleeper body 1 as described in any of the embodiments above. See also Figure 1 In this embodiment, the rear of the berth body 1 is fixed to the berth tilting structure 2. The pins in the berth tilting structure 2 are tightly engaged with each connecting rod, forming a stable six-bar tilting mechanism assembly. There are two berth tilting structures 2, arranged on one side of the rear of the berth body 1. Except for the berth tilting structure 2, the entire berth assembly is protected by a skin, thus forming an aesthetically pleasing enclosed assembly.

[0066] In one exemplary embodiment, a pull-out table assembly 3 is also installed at the rear of the sleeper body 1, such as... Figure 1 , Figure 7 , Figure 8As shown, a pull-out table assembly 3 is provided on the base plate 12 of the sleeper body 1; the pull-out table assembly 3 includes a slide rail 32 and a table body 31 installed on the base plate 12, and the table body 31 is fixedly connected to the movable part of the slide rail 32.

[0067] In this embodiment, the structure of the sleeper body 1 is as follows: Figure 7 As shown, the assembly includes a base plate 12, on which a soft pad 11 is provided. Limiting blocks 13 are also provided on the outer surface of the base plate 12. There are two limiting blocks 13, each fixing a guide frame 14. The two guide frames 14 are located on both sides of the tabletop body 31 and slide in cooperation with the sides of the tabletop body 31. The two guide frames 14 are used to guide and restrict the tabletop body 31 from both sides when it is pulled out, preventing excessive shaking during the pulling process and ensuring its stability.

[0068] In this embodiment, the limiting block 13 is fixed to the base plate 12 by bolts, and the guide frame 14 is fixed to the limiting block 13 by bolts. The guide frame 14 has an L-shaped structure, which limits the pull-out table body 31 from the side and bottom. The limiting structure is simple and reliable, so that there is no large amount of shaking during the pulling and retraction process, ensuring the stability of its movement. The slide rail 32 is a three-section slide rail. The outer rail is fixed to the base plate 12 by screws, and the inner rail is the movable part, which is fixed to the table body 31 by screws. The handle 33 is fixed to the table body 31 by screws.

[0069] Pulling the tabletop body 31 moves the movable part of the slide rail 32 and the base plate 12, pulling the tabletop body 31 to one side of the base plate 12, and the pull-out tabletop assembly 3 is in use; pushing the tabletop body 31 overlaps the tabletop body 31 with the base plate 12, and the pull-out tabletop assembly 3 is in storage, locked by the locking mechanism of the slide rail 32. During operation, the tabletop body 31 can be pulled outward and pushed inward by operating the handle 33.

[0070] The vehicle sleeper assembly of this embodiment integrates a pull-out table assembly 3, which is reliably sliding, has a large panel size, and is hidden within the sleeper assembly. This saves space in the lower frame of the sleeper and enhances the functionality of the sleeper. Integrating the pull-out table assembly 3 with the lower sleeper enhances the home-like feel of the driver's cab and lays the foundation for further space transformation. It not only provides space for dining and entertainment but also avoids modifications to the sleeper frame. It has a high degree of modularity, expandability, and portability, solving the problem that most sleeper berths on the market only have the function of lying down and resting, resulting in relatively limited functionality.

[0071] In this embodiment, the vehicle sleeper assembly is connected to the table body 31 by a self-locking slide rail 32 hidden inside the sleeper assembly. The limiting and guiding structure hidden inside the sleeper assembly ensures the convenience and stability of the table during its pull-out and use.

[0072] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
