Description

Technical Field

[0001] This utility model belongs to the field of vehicle engineering technology, specifically an adjustable cab sleeper assembly. Background Technology

[0002] During long-distance freight transport, drivers will make temporary stops at rest areas or service areas to rest and recuperate. To ensure that drivers can get sufficient rest in the vehicle, fixed sleeper berths are usually installed in the cab.

[0003] In current technology, the sleeper berth in the cab is rigidly connected to the cab chassis, side wall or roof structure by bolts, welding or embedded parts.

[0004] Fixed sleeper berths in driver's cabs lack adjustment and extension functions, resulting in inefficient space utilization and failure to meet comfort requirements. Therefore, an adjustable sleeper berth component for driver's cabs is proposed to address these issues. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] Please see Figures 1-4 This utility model provides an adjustable driver's cab sleeper assembly, including a base 1, a left mattress 2 fixedly connected to the top of the base 1, a bolt block 11 fixedly connected to the side wall of the base 1, a bolt 111 inside the bolt block 11, a protruding plate 12 fixedly connected to the side wall of the base 1, a gear rack 121 slidably connected to the top of the protruding plate 12, a gear 13 on the side wall of the left mattress 2, a first connecting rod 14 on the outside of the gear 13, a first fixing post 15 at one end of the first connecting rod 14, a fixing plate 16 fixedly connected to the top of the base 1, a fixing plate protrusion 161 fixedly connected to the side wall of the fixing plate 16, a second connecting rod 17 sleeved on the outer wall of the fixing plate protrusion 161, and a first fixing post 15 at one end of the second connecting rod 17. There is a second fixed column 171, and a base protrusion 18 is fixedly connected to the side wall of the base 1. A third connecting rod 19 is sleeved on the outer wall of the base protrusion 18. A third fixed column 191 is provided at one end of the third connecting rod 19. The gear 13 is connected to the first fixed column 15 through the first connecting rod 14, and the rotational motion of the gear 13 is converted into the lifting power of the right mattress 4. The second connecting rod 17 and the third connecting rod 19 form a lever fulcrum through the fixed plate protrusion 161 and the base protrusion 18, respectively. The three of them constitute a stable structure to ensure that the right mattress 4 is subjected to uniform force during the adjustment process and avoids unilateral tilting. The gear 13 is rotated by the adjusting bolt 111, thereby realizing the lifting and translation of the right mattress 4 above the left mattress 2.

[0024] Specifically, a positioning plate 21 is fixed to the bottom of the left mattress 2, a sub-limiting post 22 is fixed to the surface of the positioning plate 21, and a main limiting post 23 is fixed to the surface of the positioning plate 21. The main limiting post 23 cooperates with the corresponding arc-shaped hole 34 and the sub-limiting post 22 cooperates with the slot 35 to ensure that the extension pad 3 moves along the preset trajectory during the adjustment process, avoiding deviation or jamming.

[0025] Specifically, the left mattress 2 has an extension pad 3 on its side wall. A hinge block 31 is fixed to the bottom of the extension pad 3, and a connecting strip 32 is fixed to the bottom of the hinge block 31. A limiting plate 33 is fixed to the bottom of the connecting strip 32. A slot 35 is provided at the center of the surface of the limiting plate 33, and an arc-shaped hole 34 is provided on the side of the surface of the limiting plate 33 near the slot 35. Through the arc-shaped hole 34 of the limiting plate 33, the unfolding trajectory of the extension pad 3 is limited to a smooth arc, avoiding jamming or collision during unfolding and improving the smoothness of operation. The slot 35 can form a snap-fit ​​structure with the dividing limiting post 22 at the bottom of the left mattress 2. When the extension pad 3 is fully unfolded, the dividing limiting post 22 is embedded in the slot 35 to achieve mechanical locking and prevent accidental folding during use. The extension pad 3 can be unfolded from a vertical storage state to a horizontal use state through the hinge block 31, instantly increasing the width of the bed to meet the needs of temporarily adding a sleeping berth, while also saving lateral space during storage.

[0026] Specifically, the left mattress 2 has a right mattress 4 on its side wall, and the bottom of the right mattress 4 has a movable support leg 5. A second fixed post 171 is fixed to one corner of the surface of the right mattress 4, a first fixed post 15 is fixed to the side of the surface of the right mattress 4 away from the second fixed post 171, and a third fixed post 191 is fixed to the side of the surface of the right mattress 4 close to the second fixed post 171. The movable support leg 5 can be freely extended and retracted to adjust the height to adapt to different ground environments and avoid shaking. When the right mattress 4 is unfolded or the angle is adjusted, the movable support leg 5 provides synchronous support, distributes pressure, and prevents it from tipping over. When not in use, the right mattress 4 can be folded up above the left mattress 2 along with the movable support leg 5 to save sleeping space.

[0027] Specifically, a main limiting post 23 is slidably connected to the inner wall of the arc-shaped hole 34, and a secondary limiting post 22 is slidably connected to the inner wall of the slot 35. When the main limiting post 23 slides along the inner wall of the arc-shaped hole 34 and the secondary limiting post 22 slides along the inner wall of the slot 35, the extended pad 3 is forced to move along a preset arc, thus avoiding skewing caused by uneven force.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
