[0002] With the development of vehicle interior technology and the increasing requirements of users, creating a perfect living space through structural concealment and space transformation has become an important part of vehicle design. Conventional vehicle interior design includes means such as large-travel sliding seats and flip berths inside the vehicle to adjust and change the interior space and expand the functionality of the interior space so that it can be used for dining, entertainment or rest. The changes in the use and storage status of the berth can greatly change the interior space. Due to the special function of the berth, the design of the flip structure connecting the berth to the interior of the vehicle needs to consider both stability and space occupancy.

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

[0042] Referring to Fig. 1-Fig. 3, Fig. 1-Fig. 3 show a vehicle berth flipping structure in one embodiment of the present invention. The vehicle berth flipping structure 2 comprises a flipping structure fixing member 21, a berth fixing member 26 and a flipping connecting rod structure.

[0043] Continuing to refer to Figures 1 to 3, the flip structure fixing member 21 is used to be fixedly connected to the internal structural members of the vehicle; the berth fixing member 26 is used to be fixedly connected to the berth body 1; the flip connecting rod structure connects the flip structure fixing member 21 and the berth fixing member 26, and is used to achieve an angle change between the berth fixing member 26 and the flip structure fixing member 21; wherein, after the berth body 1 is flipped to the use state, the flip connecting rod structure is self-locking, playing a role in supporting the berth body 1.

[0044] The above-mentioned berth fixing parts 26 are detachably fixedly connected to the bottom plate 12 of the berth body 1, and the berth body 1 is protected by a skin as a whole, so that the appearance of the berth body 1 is beautiful; the flip structure fixing parts 21 are fixedly connected to the internal structural parts of the vehicle, and the internal structural parts of the vehicle can be the rear enclosure structure of the cab, or other internal frame structures; when the berth body 1 is flipped over and is in a use state, as shown in Figure 1 and the state view a in Figure 2, the berth body 1 is flipped upward and is in a storage state when not in use, as shown in the state view b in Figure 2; during the change between the use state and the storage state of the berth body 1, the flip connecting rod structure itself changes dynamically, and supports the flat berth body 1 from the bottom of the berth body 1 when in use, and supports the upright berth body 1 from the lower side of the berth body 1 when in the storage state.

[0045] The vehicle berth flipping structure of the present embodiment adopts a flipping connecting rod structure to connect the flipping structure fixing part 21 connected to the internal structural part of the vehicle and the berth fixing part 26 connected to the berth body 1. The berth body 1 can be supported after flipping through the dynamic change of the flipping connecting rod structure itself, so that the vehicle berth flipping structure occupies a small space and has a simple connection structure and is easy to operate.

[0046] FIG2 is a schematic diagram showing a state of a sleeper assembly for a vehicle in an embodiment of the present invention. In some embodiments, after the sleeper body 1 is flipped over to the use state, the angle between the sleeper fixing member 26 and the flip structure fixing member 21 changes to 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 with the rear enclosure structure of the cab.

[0047] Referring to Figures 3 to 6, Figure 3 shows a schematic structural diagram of a vehicle berth flip structure in an embodiment of the present invention, wherein the flip link structure comprises an outer ring deformable link assembly and an inner ring deformable link assembly; one end of the outer ring deformable link assembly is hinged to the berth fixing member 26, and the other end of the outer ring deformable link assembly is hinged to the flip structure fixing member 21; one end of the inner ring deformable link assembly is hinged to the berth fixing member 26, and the other end of the inner ring deformable link assembly is hinged to the flip structure fixing member 21. The outer ring deformable link assembly is coupled and linked to the inner ring deformable link assembly.

[0048] FIG5 shows a stereoscopic view of the vehicle sleeper flip structure of this embodiment (in use state), and FIG3 to FIG5 are two initial and final states of the flip process. During the flip process of the sleeper body 1, the deformation track of the outer ring deformable link assembly is located outside the deformation track of the inner ring deformable link assembly. During the coupling and linkage process of the outer ring deformable link assembly and the inner ring deformable link assembly of the flip link structure, the overall shape and stress state of the two link assemblies change synchronously, realizing the deformation of the flip link structure and the change of the shape and position of the supporting structure.

[0049] Continuing to refer to 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 flip structure fixing piece 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 piece 26; the middle part of the first outer ring link 22 is coupled to the inner ring deformable link assembly.

[0050] Continuing to refer to 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 flip structure fixing piece 21, the other end of the first inner ring link 23 is hinged to the middle part of the second inner ring link 24, one end of the second inner ring link 24 is hinged to the berth fixing piece 26, and the other end of the second inner ring link 24 is hinged to the middle part of the first outer ring link 22.

[0051] Among them, the two hinged positions on the flip structure fixing part 21 are arranged at intervals, and the two hinged positions on the berth fixing part 26 are arranged at intervals, ensuring that the deformation trajectory of the outer ring deformable connecting rod assembly is located outside the deformation trajectory of the inner ring deformable connecting rod assembly.

[0052] Referring to FIG3 , the first outer ring link 22 is a curved rod, and the first outer ring link 22 includes a first rod segment and a second rod segment, and the axis angle between the first rod segment and the second rod segment is an obtuse angle. The connection between the first rod segment and the second rod segment is hinged to the second inner ring link 24, and the second inner ring link 24 is located on the inner side of the obtuse angle, so that the overall configuration of the outer ring deformable link assembly is in the shape of a curve, and there are four hinge points on the outer ring deformable link assembly, all of which are on the deformation trajectory of the outer ring deformable link assembly. The second outer ring link 25, the first inner ring link 23, and the second inner ring link 24 are all straight-line-shaped, and there are four hinge points on the inner ring deformable link assembly, but three of them are located on the deformation trajectory of the inner ring deformable link assembly, and the other hinge point realizes the coupling and linkage of the outer ring deformable link assembly and the inner ring deformable link assembly, and the above hinge points are all in the form of pin connection. The overall shape change of the outer ring deformable connecting rod assembly and the inner ring deformable connecting rod assembly is divided into two deformation areas, the first deformation area is located on the side of the berth fixing part 26, and the second deformation area is located on the side of the flip structure fixing part 21.

[0053] When the berth body 1 is in the stowed state, as shown in FIG3 , the area of ​​the first deformation zone is compressed and the area of ​​the second deformation zone is increased. Under the action of gravity of the berth body 1, the second inner ring link 24 transmits the force to the first inner ring link 23 and the first outer ring link 22, so that the first inner ring link 23 and the first outer ring link 22 have a tendency to rotate away from the berth body 1 around the hinge point with the flip structure fixing part 21 and are limited, so that the berth flip structure 2 plays the role of supporting the berth body 1 from the lower side of the berth body 1.

[0054] When the berth body 1 is flipped, the gravity of the berth body 1 acts on the second inner ring link 24 and the second outer ring link 25, causing the relative distance between the two to change and the area of ​​the first deformation zone to increase. Due to the coupling linkage between the outer ring deformation link assembly and the inner ring deformation link assembly, the area of ​​the second deformation zone decreases.

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

[0056] The vehicle berth flipping structure 2 of the present embodiment has a six-link linkage structure composed of an outer ring deformable link assembly and an inner ring deformable link assembly, which ensures stability and reliability during the flipping of the berth body 1 while saving layout and flipping space. The various link structures support each other, and the state of the berth flipping structure 2 can be locked when the berth body 1 is in use, supporting the berth body 1 from the bottom of the berth body 1. When the berth body 1 is in the storage state, the berth body 1 is supported from the bottom of the berth body 1, and the compact link structure is used to achieve support in different states at one side of the berth body 1.

[0057] In an exemplary embodiment, as shown in FIG. 5-FIG . 6 , a flip link structure includes two groups of outer ring deformable link assemblies and inner ring deformable link assemblies, 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 the connecting plate 28 is two pieces, 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, so as to enhance the strength and load-bearing effect 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, as shown in FIG5 and FIG6, a plurality of connecting rods are all sheet-like structures and are arranged in layers, wherein the second outer ring connecting rod 25 is located at the innermost side and is located in the same swinging 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. As shown in FIG6, the maximum spacing between the two first outer ring connecting rods 22 is distance a, the spacing between the two hinged ear plates on the berth fixing member 26 is distance b, the spacing 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 flip connecting rod structure presents different nested cross sections, so as to realize the flexible change of the relative position of each connecting rod during the flipping process.

[0060] In an exemplary embodiment, as shown in Fig. 5-Fig. 6, a friction member 27 is provided at the hinge of the inner ring deformable link assembly and the flip structure fixing member 21, which is used to increase the friction force during the flipping process of the sleeper body 1. That is, the friction member 27 is provided at the hinge of the first inner ring link 23 and the flip structure fixing member 21, and the rotation of the first inner ring link 23 is limited by friction force to achieve locking of the storage state.

[0061] In an exemplary embodiment, the friction member 27 is made of nylon or other deformable, wear-resistant non-metallic material with a certain amount of elastic deformation. The friction member 27 is located between the pin shaft 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 connecting rod assembly and the inner ring deformable connecting rod assembly is provided with a friction member 27. A hole-pin fit and a shaped surface contact are formed at each hinge point, and the compression amount and clearance of each matching relationship are adjusted by changing the thickness of the friction member 27, so that the movement of the berth body 1 is stable during the flipping process, and a friction pair with reliable locking force is provided after the berth is flipped to 90°. That is, a friction and interlocking structure is provided at the hinge point in the six-link linkage structure, so that the stability of the berth body 1 after flipping is achieved, and the user's hands are freed while the convenience of taking and placing objects is improved; the pin shafts of each hinge point are closely matched with each connecting rod to form a flipping mechanism capable of stable movement, and the compression amount and matching amount of each connecting rod can be adjusted by adjusting the friction member 27, and the operating force and locking force of the berth flipping structure 2 are controlled and adjusted by changing the thickness of the friction member 27.

[0063] The vehicle berth flipping structure 2 of this embodiment can ensure the stability and reliability of the flipping process of the berth body 1 through the close cooperation of the connecting rod structure, and can achieve stable movement during the flipping process without the use of auxiliary supporting structures such as gas struts, and can also achieve locking of the berth body 1 in the storage state.

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

[0065] In an exemplary embodiment, the present invention provides a vehicle sleeper assembly including a vehicle sleeper flip structure 2 and a sleeper body 1 as described in any of the above embodiments. Referring to FIG1 , the rear portion of the sleeper body 1 of this embodiment is fixed to the sleeper flip structure 2, and the pins in the sleeper flip structure 2 are tightly matched with each connecting rod, forming a six-link flip mechanism assembly capable of stable movement. There are two sleeper flip structures 2, which are arranged on one side of the rear portion of the sleeper body 1. In addition to the sleeper flip structure 2, the sleeper assembly is protected by a skin as a whole, thereby forming a closed assembly with a beautiful appearance.

[0066] In an exemplary embodiment, a pull-out table assembly 3 is also installed at the rear of the berth body 1. As shown in Figures 1, 7 and 8, the pull-out table assembly 3 is provided on the bottom plate 12 of the berth body 1; the pull-out table assembly 3 includes a slide rail 32 and a table body 31 installed on the bottom 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 berth body 1 is shown in FIG. 7 , including a bottom plate 12, on which a cushion 11 is arranged, and a limit block 13 is also arranged on the outer surface of the bottom plate 12, and the number of the limit blocks 13 is two, and two limit blocks 13 are respectively fixed with a guide frame 14, and the two guide frames 14 are located on both sides of the table board body 31, and are slidably matched with both sides of the table board body 31. The two guide frames 14 are used to guide and limit the table board body 31 from both sides of the table board assembly 3 when the table board body 31 is pulled out, so as to avoid excessive shaking of the table board body 31 during the pulling out process and ensure the stability of its movement process.

[0068] In this embodiment, the limit block 13 is fixed to the base plate 12 by bolts, and the guide frame 14 is fixed to the limit block 13 by bolts; the guide frame 14 is an L-shaped structure, which limits the pull-out table board body 31 from the side and the bottom. The limiting structure is simple and reliable, so that there is no large shaking during the pulling and retracting process, thereby ensuring the stability of its movement process; 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 board body 31 by screws; the handle 33 is fixed to the table board body 31 by screws.

[0069] When the table board body 31 is pulled, the movable part of the slide rail 32 moves with the bottom plate 12, and the table board body 31 is pulled to the side of the bottom plate 12, and the pull-out table board assembly 3 is in the use state; when the table board body 31 is pushed, the table board body 31 overlaps with the bottom plate 12, and the pull-out table board assembly 3 is in the storage state, which is locked by the locking mechanism of the slide rail 32. During operation, the table board body 31 can be pulled outward or pushed inward by operating the handle 33.

[0070] The vehicle sleeper assembly of this embodiment integrates a pull-out table assembly 3 that can slide reliably, has a large surface size, and is hidden in the sleeper assembly, thereby saving space in the frame below the sleeper and improving the functionality of the sleeper. Integrating the pull-out table assembly 3 with the lower sleeper improves the degree of home-likeness inside the cab, laying the foundation for further space transformation, not only providing space for dining and entertainment, but also avoiding changes to the sleeper frame, with a very high degree of modularity, expandability, and portability, solving the problem that sleepers on the market generally only have the function of lying down and resting, and have relatively single functionality.

[0071] The vehicle berth assembly of the present embodiment is connected to the table board body 31 by a self-locking slide rail 32 hidden inside the berth assembly. The limiting and guiding structures hidden inside the berth assembly ensure the convenience and stability of the table board during pulling out and use.

[0072] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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 above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
