Description

Technical Field

[0001] This invention relates to the field of truck folding sleeper technology, specifically a truck cab folding sleeper and its connecting parts. Background Technology

[0002] Sleeper cars are a special type of vehicle with a unique appearance and functions, which can meet more travel needs. Long-distance transportation requires a high level of comfort in the cab, and the sleeper space is an important indicator of comfort. Widening the sleeper berth can effectively improve the driver's sleep quality in the vehicle, and users pay close attention to this indicator.

[0003] Chinese patent (application number CN201711285859.1) discloses a foldable and flip-up sleeper berth. By widening the berth through a flip-up mechanism and manually adjusting it via a flip-up guide rail, the maximum width reaches 1100mm when unfolded, perfectly conforming to the design concept of a "couple's bed." During normal driving, the berth can be folded up, not occupying any space in the driver's cab. This foldable and flip-up sleeper berth is easy to install, with a simple, sturdy, and durable folding and flipping structure, suitable for the daily rest of a family of three.

[0004] While the aforementioned foldable and flip-up sleeper berths can be folded and widened, they only use a single support mechanism to support the middle position of the entire sleeper berth, resulting in poor stability and easy swaying in other sleeper positions. Furthermore, due to the limited space in the truck cab, the size of the truck cab sleeper berth is relatively small, generally only accommodating one person's rest, not two people's. This can lead to driver fatigue and affect the comfort of the truck cab sleeper berth, which is not conducive to the use of the foldable sleeper berth and its connecting parts in the truck cab.

An extension plate 8 is fixedly installed on the left end face of each L-shaped insert plate 7. Through the setting of the L-shaped insert plate 7, the extension plate 8 can be snapped and fixed, so that the extension plate 8 can be assembled onto the folding board 5 to increase the area of ​​the berth. Two U-shaped telescopic plates 99 are slidably connected to the front end face of the berth board body 1. The front end face of each U-shaped telescopic plate 99 is snapped with a positioning plate 9.

[0036] The front ends of the two positioning plates 9 are respectively connected to the first support plate 10 and the second support plate 11. The lower end of the first support plate 10 is threaded with two long threaded feet 12, and the lower end of the second support plate 11 is threaded with a short threaded foot 13. By installing and using the long threaded feet 12 and the short threaded feet 13, the support height can be adjusted using the two sets of threaded feet to support the first support plate 10 and the second support plate 11 respectively. At this time, the two support plates and the two U-shaped telescopic plates 99 can simultaneously support the folding turntable 5 and the extension plate 8 at the four sides and the center, improving the stability of the berth.

The rear ends of the two sliding protrusions 27 are connected to the inner side of the connecting blocks 26 with connecting springs 28.

[0042] The upper end faces of the two connecting blocks 26 are each snapped with a mounting block 29. Through the installation and use of the sliding protrusion 27 and the connecting spring 28, pulling the sliding protrusion 27 will compress the connecting spring 28, allowing the sliding protrusion 27 to release the limit on the mounting block 29, so as to disassemble the protective mechanism. The front end faces of the two mounting blocks 29 are slidably snapped with the rear end faces of the sliding protrusion 27, and the upper end faces of the two mounting blocks 29 are connected with a vertical rod 30.

[0043] An elastic band 31 is arrayed between the two vertical bars 30. The elastic band 31 can prevent resting personnel from rolling off the bunk, thus better protecting them. It is also convenient to disassemble and store. Vertical baffles 32 are installed on the upper surfaces of the first fixing block 22 and the second fixing block 23. The vertical baffles 32 can play a certain limiting role to protect resting personnel. The vertical baffles 32 are located in front of the elastic band 31.

[0045] The upper surfaces of the first fixing block 22 and the second fixing block 23 are provided with circular grooves 33, which are adapted to the vertical baffle 32. The lower surface of the vertical baffle 32 is engaged with the upper surface of the first fixing block 22 and the second fixing block 23 through the circular grooves 33.

[0046] A connector for a folding sleeper berth in a truck cab, the connector comprising:

[0047] A combined frame 34 is snapped between a fixed base 3 and a folding rotating plate 5. A protruding plate 35 is fixedly connected to the left end face of the fixed base 3. A support base 36 is slidably connected to the upper end face of the protruding plate 35. The lower side of the support base 36 passes through the protruding plate 35 and extends to the lower end face of the protruding plate 35. A mounting spring 37 is arrayed between the support base 36 and the inner side face of the protruding plate 35. A base plate 38 is connected to the lower end face of the support base 36. Two rotating plates 39 are rotatably connected to the lower end face of the fixed base 3.

[0048] In use, this invention involves pulling out two U-shaped telescopic plates 99 from the main body 1 of the berth, then threading three short threaded support legs 13 onto the underside of the second support plate 11. Next, the positioning plate 9 on the second support plate 11 is inserted in front of the U-shaped telescopic plates 99. Then, the folding rotating plate 5 is rotated downwards, allowing it and the connecting rotating plate 4 to rotate down from the bed board 2. This positions the folding rotating plate 5 within the U-shaped telescopic plates 99 and the second support plate 11, providing stable support. Folding plate 5 is flipped and folded, and then three long threaded feet 12 are threaded onto the bottom of the first support plate 10. Then, the positioning plate 9 at the first support plate 10 is inserted into the front of another U-shaped telescopic plate 99. Then, the L-shaped insert 7 at the extension plate 8 is inserted into the two square plates 6 of the folding plate 5. In this way, the U-shaped telescopic plate 99 and the long threaded feet 12 can stably position the extension plate 8, so as to increase the width of the entire truck cab sleeper by using the folding plate 5 and the extension plate 8, and improve the comfort of the truck cab sleeper.

[0049] By rotating the movable horizontal plate 15 upwards, it is made to fit and support the extension plate 8 below. Then, the limiting plate 16 is inserted into the first mounting base 14 to fix the movable horizontal plate 15. Next, the support plate 17 is rotated downwards, and the second movable plate 19 at the first movable plate 18 is stretched so that the second movable plate 19 can enter the interior of the second mounting base 20. Then, the insert 21 is fixed into the second mounting base 20. In this way, the two movable plates and the movable horizontal plate 15 can form a stable triangular state, which further improves the stability of the folding sleeper and allows the folding sleeper to support drivers with heavier weights.

[0050] By rotating the embedded plate 24 into the second fixing block 23 at the extension plate 8, and then rotating the bolt 25 to install and fix the embedded plate 24, the embedded plate 24 can make the connection between the folding plate 5 and the extension plate 8 more reliable and increase the stability between the two. Then, the two mounting blocks 29 are inserted into the two connecting blocks 26. At this time, the mounting blocks 29 will compress the sliding protrusion rod 27 with the connecting spring 28 installed, so that the sliding protrusion rod 27 can be embedded into the mounting blocks 29 to install and fix the two mounting blocks 29. Then, the elastic band 31 at the two vertical bars 30 can surround the folding berth to block and protect the resting personnel and improve the safety of the truck cab berth.

[0051] By inserting the merging frame 34 into the fixed base 3 and the folding rotating plate 5, the merging frame 34 can be positioned to connect the rotating plate 4. Then, the base plate 38 is pushed upward, so that the support seat 36, which is equipped with the mounting spring 37, can fit and support the bottom of the connecting rotating plate 4. Next, the two rotating plates 39 are rotated to the base plate 38, so that the two rotating plates 39 can limit and support the entire support seat 36, so that the support seat 36 can form the connecting part of the folding berth, thereby increasing the stability between the connecting parts of the folding berth.

[0052] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
