Detailed Implementation

[0025] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] It should be noted that the sleeper berth assembly of this utility model is applied to a high-roof light truck, and when unfolded, the sleeper berth assembly is located on top of the driver; when folded, the sleeper berth assembly is located on the rear side panel of the cab.

[0027] A sleeper assembly according to an embodiment of the present invention includes a panel component, which includes a first panel 1, a second panel 2, and a third panel 3. The second panel 2 and the third panel 3 are pivotally connected to the first panel 1, and the second panel 2 and the third panel 3 are arranged at intervals along the length direction of the first panel 1. The panel component has a folded position and an unfolded position. In the folded position, the second panel 2 and the third panel 3 can be folded and stored around the pivot axis to the side wall of the cab. In the unfolded position, the first panel 1, the second panel 2, and the third panel 3 can be unfolded and laid flat in the cab, and the upper surfaces of the first panel 1, the second panel 2, and the third panel 3 are flush.

[0028] See Figures 1 to 4 As shown, the board component includes three boards, namely the first board 1, the second board 2 and the third board 3. When the sleeper berth is not in use, the board component is in a folded state. When the outer sleeper berth assembly is needed, the board component can be unfolded. When the board component is unfolded, the upper surfaces of the first board 1, the second board 2 and the third board 3 are flush.

[0029] It should be noted that the second panel 2 and the third panel 3 can be deployed in the front-rear direction relative to the first panel 1, or the second panel 2 and the third panel 3 can be deployed in the left-right direction relative to the first panel 1.

[0030] The sleeper berth assembly of this utility model comprises a first plate 1, a second plate 2, and a third plate 3, forming a plate component. The second plate 2 and the third plate 3 are pivotally connected to the first plate 1 and spaced apart along its length, allowing the plate component to have both folded and unfolded states. In the folded position, the second plate 2 and the third plate 3 can be folded and stored around the pivot axis to the side wall of the cab, effectively freeing up the overhead space of the cab and solving the problem of a cramped feeling when driving high-roof vehicles. In the unfolded position, the first plate 1, the second plate 2, and the third plate 3 unfold and lay flat inside the cab, with their upper surfaces remaining flush, forming a flat and reliable living compartment support surface, meeting the rest and usage needs of the driver and passengers. The foldable design enables the functional switching between driving and living spaces, balancing spatial comfort during driving and convenience when parked. It also allows for the folding and unfolding of the sleeper berth, improving the user experience.

[0031] In some embodiments, the third plate 3 is provided with a step portion 4 on the side away from the first plate 1, and in the unfolded position, the step portion 4 is adapted to contact the support plate in the driver's cab.

[0032] Optionally, the lower end face of the second plate 2 and / or the third plate 3, away from the first plate 1, is provided with a step 4. When the plate components are unfolded, the second plate 2 and the third plate 3 contact the support plate in the cab. The support plate in the cab is a permanent component and can be installed above the windshield, and the support plate is horizontally arranged. By using the support plate and the step 4, the support stability of the entire plate component can be improved, thereby improving the safety of the sleeper assembly.

[0033] See Figures 1 to 3 As shown, the first support component 5 is symmetrically arranged in the left-right direction. The upper end of the first support component 5 is pivotally connected to the first plate 1, and the lower end of the first support component 5 is pivotally connected to the side wall of the cab. For example, see Figure 3 and Figure 4 As shown, the first support component 5 includes a first support base 51 and a telescopic rod 52. One end of the telescopic rod 52 is pivotally connected to the first plate 1, and the other end of the telescopic rod 52 is pivotally connected to the first support base 51. The first support base is connected to the side wall of the cab. In the unfolded position, the plate component is in contact with the upper surface of the first support base.

[0034] The telescopic rod 52 is pivotally connected at both ends to the first plate 1 and the first support base 51, respectively, enabling the plate to rotate around its axis flexibly during folding. The first support base 51 is fixedly connected to the side wall of the cab, providing a stable load-bearing foundation for the overall structure. In the unfolded position, the plate component is in direct contact with the upper surface of the first support base 51, allowing the weight and load of the plate to be directly transferred to the base and the side wall of the cab through a large-area contact, significantly enhancing the support stability and load-bearing capacity of the berth in the unfolded state. This structure, through the adjustment of the telescopic rod 52 and its coordination with the base support, balances folding flexibility with unfolding stability.

[0035] The telescopic rod 52 is a hydraulic rod. The upper end of the telescopic rod 52 is pivotally connected to the first plate 1, and the lower end of the telescopic rod 52 is pivotally connected to the first support base 51. The first support base 51 is fixed on the side walls of the left and right sides of the cab, and the upper surface of the first support base 51 is flat. When the plate components are unfolded, the connection between the first plate 1 and the second plate 2 contacts the upper surface of the first support base 51 on the left side, and the connection between the first plate 1 and the third plate 3 contacts the upper surface of the first support base 51 on the right side.

[0036] Two first support components 5 are symmetrically arranged along the length of the first plate 1, with one end pivotally connected to the first plate 1 and the other end connected to the side wall of the cab. This symmetrical arrangement ensures that the load borne by the first plate 1 during unfolding is evenly distributed to the side walls of the cab, effectively improving the overall structural stability and load-bearing capacity of the sleeper assembly. The pivotal design provides reliable hinged support when the plate is unfolded and also allows the plate to rotate around its axis during folding, ensuring smooth folding and unfolding operations. This structure ensures stable support for the plate without compromising its functional requirements for shape transformation.

[0037] In some embodiments, the sleeper assembly further includes a second support 6, which is connected to the side wall of the cab and is located on the side adjacent to the second plate 2. In the unfolded position, the lower end face of the second plate 2 contacts the upper end face of the second support 6.

[0038] See Figure 4 As shown, the second support base 6 and the first support base are arranged at intervals in the front-rear direction of the cab. The second support base 6 includes a fixed plate and an unfolding plate. The fixed plate is fixed to the side wall of the cab. The unfolding plate is rotatable relative to the fixed plate and can be unfolded and retracted. When the unfolding plate is unfolded, the upper end face of the unfolding plate is horizontally arranged, and the lower end face of the second plate 2 is in contact with the upper end face of the unfolding plate in the second support base on the left side. The lower end face of the third plate 3 is in contact with the upper end face of the unfolding plate in the second support base 6 on the right side.

[0039] By setting a second support seat 6 to reinforce the second plate 2 and the third plate 3, the loads of the first plate 1, the second plate 2 and the third plate 3 can be evenly transferred to the two side walls of the cab through the symmetrically distributed support seats, which significantly improves the load-bearing balance and structural reliability of the entire sleeper assembly and avoids plate deformation or fatigue damage to connectors due to insufficient support on one side.

[0040] In some embodiments, the sleeper assembly further includes a first restraint component 7, which includes a restraint box 71, a first restraint strap 72, a first buckle 73, and a first locking seat 74. The restraint box 71 is fixed to the side wall of the cab. The first restraint strap 72 can be retracted or pulled out of the restraint box 71. The first buckle 73 is connected to the side of the first restraint strap 72 that extends out of the restraint box 71. The first locking seat 74 is installed on the side wall of the cab, and the first locking seat 74 and the restraint box 71 are arranged opposite each other in the height direction of the plate component. The first buckle 73 can be inserted into the first locking seat 74, and the first locking seat 74 can lock and unlock the first buckle 73.

[0041] See Figure 1 , Figure 5 and Figure 6As shown, the restraint box 71 is fixed to the rear side panel of the driver's cab, and the installation height of the restraint box 71 is greater than the installation height of the panel component. The restraint box 71 has a cable box inside, and one end of the first restraint strap 72 is wrapped around the cable box. The cable box can drive the first restraint strap 72 to automatically retract into the restraint box 71. It should be noted that the restraint box 71 can be a seat belt box, and the first restraint strap 72 can be a seat belt. In other words, the internal structure of the restraint box 71 is existing technology and will not be described in detail here.

[0042] The first buckle 73 is fixed on the first restraint strap 72. The first locking seat 74 is located below the plate component, and the first locking seat 74 and the restraint box 71 are arranged opposite each other in the vertical direction. There are two first restraint components 7, which are arranged at intervals in the horizontal direction. The first restraint components 7 can be used to fix the plate component in the folded state to avoid the plate movement causing safety hazards to the driver and passengers.

[0043] When the panel component is folded and stored on the side wall of the cab, inserting the first latch 73 into the first locking seat 74 and locking it will tighten the first restraint strap 72, thereby effectively restraining the panel component in the folded state. This prevents the panel from accidentally unfolding or loosening due to vibration during vehicle operation, ensuring driving safety and component stability. When the panel is unfolded to the use state, the first latch 73 disengages from the first locking seat 74, and the restraint strap retracts into the restraint box 71, avoiding interference with the normal use of the sleeper berth. At this time, the panel mainly relies on the support seat to bear the load, and the restraint component does not participate in the restraint. This ensures that the force on the support structure is clear and simplifies the user's operation process.

[0044] In some embodiments, the sleeper assembly further includes a second restraint component 8, which includes a second restraint strap 81, a second buckle 82, and a second locking seat 83. The second locking seat 83 is installed inside the second plate 2. One end of the second restraint strap 81 is fixed to the top plate of the cab. The second buckle 82 is connected to the side of the second restraint strap 81 away from the top plate of the cab. The second buckle 82 can be inserted into the second locking seat 83, and the second locking seat 83 can lock and unlock the second buckle 82.

[0045] See Figure 3 and Figure 4As shown, the second plate 2 and the third plate 3 can be folded separately. When the third plate 3 is laid flat, the second plate 2 can still be in a folded state. The second locking seat 83 is installed inside the second plate 2, and the upper end face of the second locking seat 83 is flush with the upper end face of the second plate 2. The upper end of the second restraint strap 81 is fixed to the roof of the cab. For example, the upper end fixing point of the second restraint strap 81 is located above the windshield. The second buckle 82 is fixed to the second restraint strap 81, and the second buckle 82 is movably connected to the roof of the cab. For example, the second buckle 82 is connected to the roof of the cab by a buckle or magnetic attraction. The second buckle 82 can be a seat belt buckle, and the second locking seat 83 can be a seat belt locking seat. It should be noted that the internal structure of the seat belt locking seat is an existing structure, which will not be described in detail here. The second buckle 82 can be inserted into the second locking seat 83.

[0046] When the second plate 2 is laid flat, the second latch 82 can be inserted into the second locking seat 83 to lock it, and the second restraint strap 81 is used to lift the second plate 2 to further improve the support stability of the second plate 2.

[0047] In another embodiment, the second locking seat 83 may also be installed on the roof of the cab, while the second restraint strap 81 is fixed to the second plate 2.

[0048] By incorporating a second restraint component 8, wherein a second locking seat 83 is mounted on the cab roof, a second restraint strap 81 connects to the second berth 2, and a second buckle 82 is connected to the restraint strap, the following design is employed: In the unfolded state, the second buckle 82 is inserted into and locked by the second locking seat 83 on the roof, tautning the restraint strap and applying an upward pulling force to the second berth 2. This effectively counteracts the downward bending tendency caused by the load on the berth, preventing sagging and deformation in the middle of the berth and improving its flatness and load-bearing capacity. In the folded state, the second buckle 82 disengages from the locking seat, and the restraint strap retracts with the berth, avoiding interference with the folding operation. This design, through a combination of top tension compensation and bottom support, further enhances the overall rigidity and stability of the berth in the unfolded state.

[0049] In some embodiments, the sleeper assembly further includes a climbing ladder 9 and a third locking box 10. The third locking box 10 is located on the lower end face of the third plate 3. The third locking box 10 has an opening 101 on the side facing the second plate 2. The third locking box 10 has a locking pin 102 inside. The climbing ladder 9 has a locking frame 91. The locking frame can be inserted into the third locking box 10 through the opening 101. The climbing ladder 9 has a first position and a second position. In the first position, the climbing ladder is placed horizontally on the lower end face of the third plate 3. In the second position, the locking frame 91 engages with the locking pin 102 to fix the climbing ladder tiltably on the side of the third plate 3 facing the second plate 2.

[0050] See Figures 7 to 8As shown, the third locking box 10 is located below the third plate 3. The left side of the third locking box 10 has two openings 101, which connect the outside world and the internal space of the third locking box 10. The side of the third locking box 10 away from the openings 101 is provided with a locking pin 102, which is arranged in the front-back direction. The right side of the climbing ladder is provided with a locking frame 91, which can be inserted into the third locking box 10 through the openings 101. The upper end of the locking frame 91 has a locking groove, which can engage with the locking pin 102 to lock the climbing ladder.

[0051] Optionally, an abutment block 103 can be provided on one side near the opening 101 of the third locking box 10. The abutment block 103 and the locking pin 102 are arranged in the vertical direction respectively. When the locking frame 91 and the locking pin 102 are engaged and locked, the lower end of the locking frame 91 abuts against the abutment block 103, thereby stably fixing the climbing ladder in the third locking box 10.

[0052] In some embodiments, the first plate 1, the second plate 2, and the third plate 3 have the same width, and the length of the first plate 1 is the same as the sum of the lengths of the second plate 2 and the third plate 3.

[0053] The following reference Figures 1 to 9 This describes the usage process of the sleeper berth assembly according to an embodiment of the present invention.

[0054] When the sleeper berth assembly is not in use, the panel components are folded and stored on the rear side wall of the cab, and are secured to the rear side wall of the cab by the first restraint component 7. When the sleeper berth assembly is needed, the driver or passenger presses the switch on the first locking box to unlock and disengage the first lock 73 from the first locking box. At this time, the handles at the lower ends of the third panel 3 and the second panel 2 can be pulled forward to unfold the panel components until the step portion 4 at the lower end of the third panel 3 and the second panel 2 contacts the support plate inside the cab, thus completing the unfolding of the sleeper berth assembly. At this point, a living compartment is formed between the sleeper berth assembly and the roof of the cab.

[0055] When the occupants need to rest, fold the support plate at the lower end of the second plate 2 and flip the second plate 2 downwards. Remove the climbing ladder from the lower end of the third plate 3 and push the locking frame 91 against the inner top surface of the opening 101 of the third locking box 10. When the locking groove on the locking frame engages with the locking pin 102, a sound will be made. At this time, release the climbing ladder. Under the action of gravity, the climbing ladder abuts against the abutment block 103. At this time, the climbing ladder is fixed inside the third locking box 10. The occupants enter the living compartment through the climbing ladder and pull the second restraint strap 81 to flip the second plate 2 upwards. Lock the second buckle 82 with the second locking box and use the second restraint strap 81 to provide support for the second plate 2.

[0056] It should be noted that when the climbing ladder needs to be removed, tilt the lower end of the climbing ladder upwards to make the locking frame 91 higher on the left and lower on the right, so that the locking pin 102 disengages from the locking frame 91. Then pull the climbing ladder to the left to disengage the climbing ladder from the third locking box 10. After removing the climbing ladder, it can be fixed to the lower end of the third plate 3 by means of buckles, magnetic attraction or cable ties.
