Technical Field
[0001] This utility model relates to the field of automotive interior accessories technology, and in particular to an integrated device for a hidden front table in the lower bunk. Background Technology
[0002] In long-distance transportation and RV travel scenarios, the sleeper area of a vehicle is not only an important space for drivers or passengers to rest, but also often needs to accommodate temporary dining and storage. With increasing demands for space utilization efficiency and functionality, integrating convenient and practical auxiliary devices within the limited sleeper area has become an important direction for optimizing vehicle interior design. This is especially true for commercial vehicles such as trucks, where drivers need to fully rest in the sleeper area during long-distance driving, while also requiring a platform for temporary dining or storage. Therefore, higher demands are placed on the concealment, practicality, and convenience of related devices.
[0003] Currently, existing tray table devices in sleeper berth areas of transportation vehicles generally suffer from two shortcomings: Firstly, traditional designs often employ exposed or folding tray tables, which easily occupy space or affect the comfort of the sleeper berth when not in use, and lack stability when unfolded, making it difficult to provide reliable support while the vehicle is in motion; secondly, the connection between the tray table and the main structure mostly relies on screws and other fixing components, requiring tools for replacement or maintenance, making the operation cumbersome, especially when long-term vibration in the vehicle environment causes component wear, hindering quick disassembly and replacement. Existing technology lacks an integrated device that can achieve concealed storage and stable use of the tray table without affecting the sleeper berth's resting function, while also ensuring convenient maintenance. Therefore, to address this technical problem, this application proposes an integrated device for a concealed front-mounted tray table in the lower sleeper berth. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an integrated hidden front table device for the lower berth. The hidden design conceals the table within the berth board; it can be unfolded and stably supported by locking components to meet temporary dining needs. Furthermore, the quick-release structure allows for rapid assembly and disassembly without tools, facilitating maintenance and replacement.
[0005] To achieve the above objectives, the present invention provides the following technical solution: The lower berth concealed front small table integrated device includes a berth board, a berth mat on the upper side of the berth board, a main fixing seat fixedly connected to the bottom of the berth board, a rotating block fixedly connected to the upper side of the main fixing seat, a locking component on the upper side of the rotating block, a rotating linkage first connected to the rotating block through the locking component, a reinforcing rod fixedly connected between the two sides of the rotating linkage first, a rotating linkage second rotatably connected to the front side of the main fixing seat, a quick-release component on the other end of the rotating linkage second, a small table connected to the rotating linkage second through the quick-release, and a support fixedly connected to the upper side of the berth board.
[0006] Furthermore, the locking assembly includes a second toothed plate fixedly connected to the left side of the rotating block, a connecting rod slidably connected inside the second toothed plate, a first toothed plate fixedly connected to the left end of the connecting rod, and a cam knob rotatably connected to the right side of the connecting rod.
[0007] Furthermore, the quick-release assembly includes a housing fixedly connected to the inner wall of the small dining table, with rivets inside the housing, holes in the inner wall of the housing, movable balls inside the holes, and a sliding cover slidably connected to the outer wall of the housing.
[0008] Furthermore, a groove is provided on the left side of the sleeper berth, and a connecting plate is provided inside the groove.
[0009] Furthermore, a spring is sleeved on the outer wall of the left side of the connecting rod, and the outer wall of the spring is located on the left side of the toothed plate.
[0010] Furthermore, an auxiliary plate is fixedly connected to the left side of the main fixing seat, and an auxiliary fixing seat is fixedly connected to the left side of the auxiliary plate. The outer wall of the auxiliary fixing seat is disposed on the lower side of the connecting plate.
[0011] Furthermore, a protrusion is fixedly connected to the inner wall of the right side of the sliding cover, and the outer wall of the protrusion is located on the outside of the movable ball.
[0012] Furthermore, a second spring is sleeved on the outer wall of the outer shell, the outer wall of the second spring is disposed inside the sliding cover, and the outer wall of the second spring is disposed on the left side of the protrusion.
[0013] This utility model has the following beneficial effects: 1. In this utility model, the device conceals the small table inside the sleeper berth. Covered by the sleeper mat, the small table is completely hidden within the berth structure when not in use, occupying no extra space and not affecting the driver's rest. This effectively balances the rest function of the sleeper area with the need for temporary meals. When needed, simply lift the sleeper mat and rotate to unfold the small table, allowing it to extend between the driver and passenger seats and adjust its height. A locking mechanism is included to maintain the unfolded state, ensuring the small table is stable and does not wobble during use. This provides a stable support platform for holding lightweight items such as bowls and chopsticks, achieving a convenient switching effect of "hidden without interference, ready to use upon unfolding."
[0014] 2. In this utility model, the quick-release structure design of the device greatly improves the convenience of component replacement and maintenance. Its core advantage lies in achieving quick disassembly and assembly without the need for tools through simple mechanical linkage. This design not only avoids the tedious operation of repeatedly tightening traditional screws, but also ensures flexible rotation and reliable connection during use through the automatic locking mechanism of springs and movable balls. Even after long-term use, it can maintain smooth disassembly and assembly, which is especially suitable for scenarios in vehicle environments where the table may need to be frequently replaced due to wear and tear or design updates. This effectively reduces maintenance costs and improves the practicality of the structure. Attached Figure Description

[0017] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Reference Figures 1-3 This utility model provides an embodiment of an integrated device for a concealed front table in the lower berth, comprising a berth board 2, a berth mat 1 on the upper side of the berth board 2, a main fixing seat 10 fixedly connected to the bottom of the berth board 2, a rotating block 17 fixedly connected to the upper side of the main fixing seat 10, a toothed plate 16 on the upper side of the rotating block 17, a connecting rod 13 slidably connected inside the toothed plate 16, a toothed plate 14 fixedly connected to the left end of the connecting rod 13, and a cam knob 12 rotatably connected to the right side of the connecting rod 13. The rotating block 17 is connected to a rotating connecting rod 6 via the connecting rod 13, a reinforcing rod 5 is fixedly connected between the two rotating connecting rods 16, a rotating connecting rod 7 is rotatably connected to the front side of the main fixing seat 10, a housing 19 is provided at the other end of the rotating connecting rod 7, a rivet 18 is provided inside the housing 19, a hole is opened on the inner wall of the housing 19, a movable ball 23 is provided inside the hole, and a sliding cover 21 is slidably connected to the outer wall of the housing 19. The rotating link 2 7 is connected to a small dining table 3 via a quick-release mechanism, and a support 4 is fixedly connected to the upper side of the berth board 2.
[0019] Specifically, this device can conceal the small dining table 3 inside the sleeper berth, without affecting the driver's use of the sleeper berth for rest. When eating, the sleeper berth mat 1 can be lifted up and the small dining table 3 can be rotated out for use. When in the dining state, it can be extended between the main and passenger seats and raised, and can be used to hold light items such as bowls and chopsticks. The small dining table 3 can be pulled upwards, causing rotating connecting rod 1 6 and rotating connecting rod 2 7 to rotate. The side edge of the berth 2 will provide support. At this time, turn the cam knob 12 outwards. Because the rotation axis between the cam knob 12 and the connecting rod 13 is not the center of the cam knob 12, there will be a position difference, which will cause the connecting rod 13 and the toothed plate 14 to move to the side. The serrations between the toothed plate 14 and the toothed plate 2 16 will mesh with each other, thereby fixing the rotating connecting rod 1 6 and the rotating connecting rod 2 7. Since the rotation of the small dining table 3 depends on the misalignment of the rotating connecting rod 1 6 and the rotating connecting rod 2 7, when the rotating connecting rod 1 6 and the rotating connecting rod 2 7 cannot rotate, the small dining table 3 will also be fixed to prevent the small dining table 3 from shaking unintentionally. When the device needs to be restored, simply turn the cam knob 12 again. The elasticity of the spring 15 will drive the toothed plate 14 to the left, completing the separation of the toothed plate 14 and the toothed plate 2 16. The device is secured by a screw and nut connection between the upper connecting plate 11 and the lower auxiliary fixing seat 8, connecting the rotating part of the small dining table 3 to the main body of the berth 2. The support 4 supports the small dining table 3 in the folded state and is located in the middle, so it does not interfere with the rotating linkage 1 6 and rotating linkage 2 7. Because the table may require redesign after long-term use, a quick-release structure is designed. First, the sliding cover 21 on the outer wall of the outer shell 19 can be slid to the left, aligning with the small hole at the bottom of the small dining table 3. The rivet 18 can then be inserted, and the sliding cover 21 can be released. Similarly, when disassembly is required, sliding the sliding cover 21 to the left easily separates the two parts. During this process, sliding the sliding cover 21 to the left provides space for the movement of the protrusion 20. When inserted, the protrusion 20 will move to one side. Once fully inserted, the sliding cover 21 can be released. A spring is provided on the left side of the sliding cover 21. 22. The sliding cover 21 has a limit plate on the right side, so the sliding cover 21 will be pushed to the appropriate position. The internal protrusion 20 will stay at the same level as the movable ball 23. The rivet 18 (the front of the rivet 18 has a rubber damping ring, which is not easy to fall off after insertion) has a groove on its outer wall, so the protrusion 20 abuts against one side, and the movable ball 23 will be restricted to the groove of the rivet 18. The hole inside the outer shell 19 is slightly larger than the movable ball 23, but it will not allow the movable ball 23 to go out. Therefore, the separation and installation process of the device can be easily completed without affecting the rotation requirements during the use of the device.
[0020] Reference Figures 4-6A groove is provided on the left side of the sleeper berth 2, and a connecting plate 11 is installed inside the groove. A spring 15 is fitted on the outer left side of the connecting rod 13, and the outer wall of the spring 15 is located on the left side of the toothed plate 16. An auxiliary plate 9 is fixedly connected to the left side of the main fixing seat 10, and an auxiliary fixing seat 8 is fixedly connected to the left side of the auxiliary plate 9, with the outer wall of the auxiliary fixing seat 8 located below the connecting plate 11. A protrusion 20 is fixedly connected to the inner right side of the sliding cover 21, and the outer wall of the protrusion 20 is located outside the movable ball 23. A spring 22 is fitted on the outer wall of the outer shell 19, with the outer wall of the spring 22 located inside the sliding cover 21 and on the left side of the protrusion 20.
[0021] Specifically, a groove is provided on the left side of the berth 2, and a connecting plate 11 is installed inside the groove to connect the rotating part of the device to the main body of the berth 2. A spring 15 is sleeved on the outer left side of the connecting rod 13. The outer wall of the spring 15 is located on the left side of the toothed plate 16. Utilizing the elasticity of the spring 15, the toothed plate 14 can be moved to the left when the device needs to be restored, thus separating the toothed plate 14 from the toothed plate 16. An auxiliary plate 9 is fixedly connected to the left side of the main fixing seat 10, and an auxiliary fixing seat 8 is fixedly connected to the left side of the auxiliary plate 9. The outer wall of the auxiliary fixing seat 8 is located on the lower side of the connecting plate 11. The device relies on the connection between the upper connecting plate 11 and the lower auxiliary fixing seat 8 through screws and nuts to connect the rotating part of the small dining table 3 to the main body of the berth 2. A protrusion 20 is fixedly connected to the inner right side of the sliding cover 21. The outer wall of the protrusion 20 is located outside the movable ball 23. A second spring 22 is fitted on the outer wall of the outer shell 19 (the second spring 22 has suitable elasticity and is not easy to loosen). The outer wall of the second spring 22 is located inside the sliding cover 21 and to the left of the protrusion 20. When performing a quick disassembly operation, slide the sliding cover 21 to the left, compress the second spring 22, leaving space for the movement of the protrusion 20. The protrusion 20 drives the movable ball 23 to move. After inserting the rivet 18 into the small hole at the bottom of the small table 3, release the sliding cover 21. The second spring 22 returns to its original position, and the sliding cover 21 is pushed to the appropriate position. The protrusion 20 abuts against the movable ball 23, restricting it at the groove of the rivet 18, thus achieving quick installation of the small table 3. When disassembling, slide the sliding cover 21 to the left in the same way to easily separate the small table 3 from the outer shell 19. The whole process does not affect the rotation requirements during the use of the device and can easily complete the separation and installation.
[0022] Working principle: When the small dining table 3 is unfolded to the use position, rotate the cam knob 12 outward. Due to the eccentricity between the rotation axis of the cam knob 12 and the center, rotation pushes the connecting rod 13 to move to the right. The connecting rod 13 drives the toothed plate 14 to move to the right, so that it meshes with the serrations of the toothed plate 16. At this time, the relative position of the rotating connecting rod 6 and the rotating block 17 is fixed. The rotating connecting rod 7 is connected to the small dining table 3 through a quick-release structure, and its other end is rotatably connected to the main fixing seat 10. When the rotating connecting rod 6 is locked, the movement of the rotating connecting rod 7 is also restricted, thereby achieving stable fixation of the entire small dining table 3 and preventing shaking during use. When it is necessary to unlock, rotate the cam knob 12 in the opposite direction. The elastic force of the spring 15 pulls the toothed plate 14 back to the left, separating the toothed plate 14 from the toothed plate 16 and restoring the rotational freedom of the connecting rod. Align the outer casing 19 with the connecting hole at the bottom of the small dining table 3, slide the sliding cover 21 to the left, compressing the second spring 22 and creating space for the protrusion 20 to move. After inserting the rivet 18, release the sliding cover 21, and the second spring 22 pushes the sliding cover 21 back to its original position. At this time, the protrusion 20 abuts against the movable ball 23, causing it to engage in the groove on the outer wall of the rivet 18, completing a quick lock. Slide the sliding cover 21 to the left, the protrusion 20 moves and releases the movable ball 23, causing it to disengage from the groove of the rivet 18. At this time, the rivet 18 can be pulled out directly, separating the small dining table 3 from the rotating connecting rod 7, facilitating replacement or maintenance of parts. The hole on the inner wall of the outer casing 19 is slightly larger than the movable ball 23, allowing it to move within the hole while preventing it from coming out. The second spring 22 provides continuous pressure through the sliding cover 21, ensuring that the protrusion 20 and the movable ball 23 always remain in contact, maintaining the stability of the locked state.
[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
