Detailed Implementation

[0032] This section will describe in detail the specific embodiments of the present invention. Preferred embodiments of the present invention are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present invention, but they should not be construed as limiting the scope of protection of the present invention.

[0033] Example 1:

[0034] Reference Figures 1 to 14This utility model provides a detachable and installable table and chair structure for RVs, including a mounting base and two sets of slide rails. A seat is movably mounted on each set of slide rails, and each slide rail is provided with an adjustment mechanism for adjusting the position of the seat. A mounting frame is rotatably mounted on the mounting base, and a support frame is rotatably mounted on the mounting frame. A table is detachably mounted on the mounting frame, and a slider is rotatably mounted at the end of the support frame. A vertical sliding groove is provided on the mounting base for moving and mounting the slider, and a support mechanism is provided on the mounting base for adjusting the support state of the slider. Each seat is slidably mounted with a storage rack, and the table is used to be mounted at the ends of the two extended storage racks to form a bed.

[0035] After the mounting bracket is flipped open relative to the mounting base, the mounting bracket pulls the slider upwards. The slider is then supported by a support mechanism, preventing it from moving downwards and maintaining the extended state of the mounting bracket and tabletop, thus achieving the "dining table" usage mode. When the tabletop needs to be folded up, the support mechanism releases the slider, and under gravity, the mounting bracket flips downwards, causing the slider to move down and the tabletop to be folded up. When the user needs a bed, the distance between the two seats is increased by adjusting the mechanism, and the two storage racks are pulled out. The tabletop is then removed from the mounting bracket and installed at the ends of the two storage racks to assemble a bed. This design effectively solves the problem of excessive space occupation caused by separate seating and bed installation, improving space utilization and meeting various user needs.

[0036] Specifically, the tabletop is provided with a plug, the mounting bracket is provided with a plug socket for the plug to be inserted, the tabletop is provided with a positioning hole, the plug socket is provided with a screw hole aligned with the positioning hole, a screw rod with a rotating handle structure is threadedly connected to the screw hole, and a positioning rod is provided on the screw rod to be inserted and engaged with the positioning hole.

[0037] By inserting the tabletop's insert into the socket on the mounting bracket and using the screw with the rotating handle to turn it into the screw hole, the positioning rod can be inserted into the positioning hole, thus enabling the tabletop to be detached from the mounting bracket as needed.

[0038] Example 2:

[0039] Reference Figures 1 to 14 In conjunction with the technical solution of Embodiment 1, in this embodiment, the adjustment mechanism includes a lead screw and a drive motor. The drive motor is mounted on the slide rail and is used to drive the lead screw to rotate. The seat is provided with a threaded hole that mates with the lead screw.

[0040] The drive motor is connected to the RV's power supply circuit and control system. The motor's operating status can be adjusted via buttons on the RV. For example, the RV has forward and reverse buttons; pressing these buttons will cause the drive motor to rotate the lead screw in either direction, thus adjusting the seat position. Using the RV's power supply circuit and control system to adjust the seat position is a conventional technique in this field and will not be elaborated upon further in this application.

[0041] When the drive motor drives the lead screw to rotate, it works in conjunction with the threaded hole on the seat to make the seat slide relative to the slide rail, thereby adjusting the position of the seat.

[0042] Example 3:

[0043] Reference Figures 1 to 14 In conjunction with the technical solutions of Embodiments 1 and 2, in this embodiment, the support mechanism includes a moving block, a spring, and a toggle plate. A horizontal slide groove is provided on one side of the vertical slide groove for the moving block to be moved and installed. The toggle plate is connected to the moving block. A limiting groove is provided on the mounting base for the toggle plate to be slidably installed. The spring is provided on the mounting base and pushes against the moving block to drive the moving block to extend to the vertical slide groove. The moving block is used to support the slider.

[0044] During the unfolding of the mounting bracket and tabletop, force is applied to rotate the mounting bracket. When the slider moves to the moving block, the manual movement of the actuating plate drives the moving block to retract into the horizontal slide groove. Then, the mounting bracket continues to unfold, moving the slider to the top of the horizontal slide groove. First, the external force at the actuating block is removed, and the spring drives the moving block to reset. The moving block extends out of the horizontal slide groove and is located below the slider. Then, the external force at the mounting bracket is removed, and the slider abuts against the moving block, preventing the slider from moving down. This provides support for the slider, thereby supporting the unfolding of the mounting bracket through the support frame.

[0045] When it is necessary to store the mounting rack and table, manually move the lever to drive the moving block back into the horizontal slide, release the limit on the slider, and then support the mounting rack with its own weight to drive it to flip downwards, so that the table and mounting rack can be rotated to the side of the RV to store the table and mounting rack.

[0046] Specifically, the bottom of one end of the moving block is provided with an inclined surface for the slider to push against.

[0047] By designing the bottom of one end of the movable block as a sloped structure, during the unfolding of the mounting frame and tabletop, the slider moves upward and abuts against the sloped surface. This causes the limiting block to automatically retract into the horizontal groove due to the horizontal component of the force, eliminating the need for manual movement of the actuating block. When the slider moves above the movable block, the movable block is spring-loaded and automatically pops out of the horizontal groove, with its upper end abutting against and supporting the slider. This reduces the need for manual operation of the actuating block during the unfolding of the mounting frame and tabletop, providing greater convenience for the unfolding operation.

[0048] Example 4:

[0049] Reference Figures 1 to 14 In conjunction with the technical solutions of embodiments 1-3, in this embodiment, the upper end of the storage rack is provided with a plurality of first partitions at intervals, and the seat is provided with a plurality of second partitions. The first partitions and the second partitions are at the same height, and the plurality of first partitions and the plurality of second partitions are arranged alternately and slide in cooperation with each other.

[0050] Specifically, the first partition is provided with a splicing groove, and the second partition is provided with a sliding protrusion that slides in conjunction with the splicing groove. Both ends of the groove are provided with abutment portions that limit the movement range of the sliding protrusion. When the storage rack is fully extended relative to the seat, the sliding protrusion abuts against one end of the groove.

[0051] By utilizing a structure of several first partitions and several second partitions that are staggered and slidably fitted together, the upper ends of the first partitions and the upper ends of the second partitions can be kept flush, thus keeping the bed body assembled later flush.

[0052] Specifically, insert plates are provided on both sides of the bottom of the tabletop, and slots are provided on both storage racks for inserting the insert plates. When the two insert plates on the tabletop are inserted into the slots on the two storage racks, the height of the upper surface of the tabletop is the same as the height of the upper surface of the two storage racks, effectively keeping the upper surface of the assembled bed frame flush.

[0053] The two storage racks are connected by inserting plates on the tabletop into slots on the two racks, preventing them from accidentally detaching from the tabletop.

[0054] Specifically, each of the seats is rotatably equipped with a lever for abutting against the storage rack to maintain its stored state.

[0055] After the storage rack retracts the seat, turn the lever to make it horizontal. The lever will then abut against the storage rack, preventing it from extending out of the seat and thus securing the storage rack. To move the storage rack out, turn the lever to move it away from the storage rack and release the lever from abutting the rack.

[0056] Example 5:

[0057] Reference Figure 1 , Figure 2 and Figure 6 In conjunction with the technical solutions of embodiments 1-4, in this embodiment, each of the seats is provided with a seat cushion, and a folding pad that can be folded relative to the seat cushion is connected to the seat cushion. Each of the seats is provided with a backrest cushion. The folding pad and the backrest cushion on two of the seats are used to be placed on the table and the storage rack to cooperate with the seat cushion to form a mattress.

[0058] In seat mode, the folding cushion is folded over the seat cushion, and the backrest cushion is located on the folding cushion and rests against the back of the seat. In bed mode, the table is installed on two storage racks. The folding cushion is folded over the storage racks, and the backrest cushion is moved to the table. Thus, the mattress structure consists of two folding cushions, two backrest cushions, and two seat cushions.

[0059] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
