Description

Technical Field

[0001] The utility model relates to the field of RV structures, and particularly to a folding bed for an RV. Background Art

[0002] Since RVs need to have vehicle functions, most RVs are limited by the overall size, and their internal space is even more limited. As a facility that occupies the main space, the rationality of the space utilization of the bed directly affects the size of the internal activity area of the RV and the living comfort.

[0003] In terms of the bed layout, there are many inconveniences in the design of many traditional RVs with fixed beds. Whether the bed is used or not, it occupies the space inside the vehicle for a long time, resulting in the inability to flexibly convert these spaces into other functional areas when rest is not needed. For example, in some RVs with a rear transverse bed layout, the position of the bed is basically fixed, making it difficult to use the large space at the rear for other purposes during the day, restricting the multi-functionality of the internal space of the vehicle and hindering people's free movement inside the vehicle.

[0004] For side-extending RVs, since the internal structure needs to be in a folded state when the side extension is retracted, the current side extension position cannot be used to place a bed. As a result, although the side-extending RV expands the internal space, the area where the bed can be arranged is still similar to that of traditional RVs. Specifically, the bed can only be arranged in areas such as the front and rear of the vehicle where there is no extension position, resulting in a problem of space waste. Summary of the Utility Model

[0005] The purpose of the present utility model is to solve the above problems by providing a folding bed for an RV, which is provided with a bed board that can be folded and stored in the storage groove of the side extension bottom board, supported by a bed frame. When the side extension of the RV is retracted, the bed board can be folded and stored well, and can be quickly propped up by means of an adjusting motor after being unfolded. This design improves the space utilization rate of the RV and realizes diverse function conversions. The adjusting motor is easy to operate, enabling the user to conveniently unfold and fold the bed board, enhancing the use experience. After the bed board is retracted, it is flush with the side extension bottom board, ensuring the flatness of the ground inside the vehicle, reducing walking obstacles, lowering the risk of bumping, and enhancing the safety and practicality of the internal space of the RV. See the following for details.

[0006] To achieve the above purpose, the present utility model provides the following technical solutions:

[0007] A folding bed for an RV provided by the present utility model includes a side extension bottom board and a bed board. A steel skeleton is fixed to the bottom side of the side extension bottom board. The bed board is arranged parallel to the upper side of the side extension bottom board. A bed frame for supporting the bed board is hinged to the top side of the steel skeleton. A storage groove for accommodating the bed frame to support the bed board to rotate downward and be retracted is vertically penetrated through the middle of the side extension bottom board;

[0008] A longitudinally extending guide frame is fixed in the middle of the steel skeleton. A transmission part is longitudinally slidably arranged inside the guide frame. An inclined strut for pulling the bed frame to rotate to support the folding of the bed board is hinged to the top side of the transmission part. An adjustment motor for supporting the longitudinal sliding of the transmission part is fixed to the bottom side of the steel skeleton.

[0009] When using the above folding bed for a motorhome and it is necessary to fold up the bed board, the adjustment motor drives the screw to rotate. By the threaded engagement of the screw with the threaded hole in the middle of the transmission block, the screw is used to push the transmission block, the transmission seat and the guide rod to slide along the guide frame. At this time, the guide rod slides away from the adjustment motor, and the articulated seat fixedly connected to the top side of the guide rod pulls the inclined strut to drive the bed frame to rotate backward, so that the bed frame drives the bed board to be retracted downward to retract the bed frame into the storage groove of the side expansion bottom plate, completing the hiding action of the bed board on the side expansion bottom plate; when it is necessary to open the bed board for use as a bed, the adjustment motor is selected in the reverse direction, the screw is used to pull the transmission block, the transmission seat and the guide rod, and the guide rod is used to drive the articulated seat to push the inclined strut, so as to push the inclined strut in the inclined state to drive the bed board to rise, completing the opening action of the bed board.

[0010] Preferably, the bottom side of the bed board is hinged to the top side of the bed frame. An articulated hole penetrates through the bottom side of the bed frame transversely. A positioning hole is provided on the top side of the guide frame corresponding to the articulated hole. An articulated shaft is inserted into the positioning hole to cooperate with the articulated hole to realize the articulated cooperation between the bed frame and the guide frame.

[0011] Preferably, the guide frame is a channel-shaped structure with an open top. The transmission part includes a guide rod extending along the length direction of the guide frame. A transmission seat is fixed to the front end of the guide rod, and a transmission block is arranged inside the transmission seat.

[0012] Preferably, a threaded hole penetrates through the middle of the transmission block longitudinally. The output end of the adjustment motor is drivingly connected to a screw passing through the threaded hole. The screw is used to rotate to drive the whole transmission part to slide longitudinally along the guide frame.

[0013] Preferably, an articulated seat is arranged at the bottom end of the inclined strut. The articulated seat is fixed to the top side of the guide rod, and the inclined strut is rotatably connected to the guide rod through the articulated seat.

[0014] Preferably, a support seat is hinged to the top end of the inclined strut. The support seat is fixed to the outside of the bed frame.

[0015] Preferably, two groups of motor seats are symmetrically arranged on both sides outside the adjustment motor. The adjustment motor is fixed to the inner side of the steel skeleton through the motor seats.

[0016] The beneficial effects are as follows: 1. In the present utility model, a bed board that can be folded and retracted to the side expansion bottom plate is provided. The bed board is supported by a bed frame and folded parallelly into the storage groove of the side expansion bottom plate, so as to ensure that the bed body is in the folded and retracted position when the side expansion position of the RV is retracted. After the side expansion position of the RV is unfolded, the bed board is quickly lifted by using an adjustment motor, enabling the bed to be arranged at the side expansion position of the RV, improving the space utilization rate, and enabling the RV to realize diversified function conversion in a limited space;

[0017] 2. At the same time, the use of the adjustment motor makes the lifting operation of the bed board easy and convenient. Even users with less strength can easily complete the unfolding and retracting actions, providing a more comfortable use experience. Moreover, after the bed board is retracted, it is flush with the side expansion bottom plate, ensuring the flatness of the vehicle interior floor, reducing the obstacles during walking, and lowering the risk of accidental bumps, further enhancing the safety and practicality of the interior space of the RV.
