Description

Technical Field

[0001] This utility model relates to the field of RVs, and in particular to a tilting and retractable lift bed. Background Technology

[0002] RVs are a type of fashionable vehicle imported from abroad. The home furnishings on the vehicle include: bedding, stove, refrigerator, cabinets, sofa, dining table and chairs, washing facilities, air conditioning, TV, audio equipment and other furniture and appliances. They can be divided into driving area, living area, bedroom area, bathroom area and kitchen area.

[0003] Currently, the beds in motorhomes are all placed on the ground. Even if they are folded, they will occupy the frequently used activity areas inside the vehicle, making the interior space cramped, while most of the overhead space is wasted; this is especially true for sloping-roof motorhomes, where the utilization rate of overhead space is even lower. Utility Model Content

[0004] To address the shortcomings of the existing technology, the main objective of this utility model is to overcome these deficiencies by disclosing a tilting and retracting lifting bed, comprising a bed body and guide components. Two sets of guide components are provided, positioned at both ends of the bed body and fixed to the carriage. Each guide component includes an upper mounting plate, a lower mounting plate, a first main connecting rod, a second main connecting rod, a first auxiliary connecting rod, and a second auxiliary connecting rod. The upper mounting plate is fixed to the carriage, and the lower mounting plate is fixed to the side of the bed body. The first main connecting rod and the second main connecting rod are hinged. The upper end of the first main connecting rod is hinged to the upper mounting plate via the first auxiliary connecting rod, and the lower end of the first main connecting rod is hinged to the lower mounting plate. The lower end of the second main connecting rod is hinged to the lower mounting plate via the second auxiliary connecting rod, and the upper end of the second main connecting rod is hinged to the upper mounting plate.

[0005] Furthermore, a first limiting part is provided at the lower end of the first main connecting rod, and a second limiting part is provided on the lower mounting plate to cooperate with the first limiting part. The maximum unfolding position of the guide assembly is limited by the cooperation of the first limiting part and the second limiting part.

[0006] Furthermore, a third limiting part is provided at the upper end of the second main connecting rod, and a fourth limiting part is provided at a corresponding position on the upper mounting plate. The third limiting part and the fourth limiting part cooperate to limit the maximum unfolded position of the guide assembly.

[0007] Furthermore, the guide assembly also includes a gas spring, which connects the upper end of the second main connecting rod to the upper mounting plate.

[0008] Furthermore, two first main connecting rods are arranged in parallel, and the first main connecting rods are respectively located on both sides of the second main connecting rod.

[0009] Furthermore, a latch is provided on the lower mounting plate, and a locking tongue is provided on the upper mounting plate. When retracted, the locking tongue engages with the latch.

[0010] Furthermore, the bed frame is equipped with handles.

[0011] The beneficial effects of this utility model are as follows:

[0012] This invention improves the space utilization of vehicles with sloping roofs by incorporating two sets of guide components on the bed frame. These guide components, through a first and second auxiliary connecting rod, cooperate with a first and second main connecting rod to achieve oblique retraction (horizontal expansion), thus enhancing the overall space utilization. Cleverly designed limiting parts on the first and second main connecting rods prevent rotation and limit the maximum expansion position of the guide components, ensuring the bed frame remains horizontal when expanded. A locking tongue and a latch are respectively installed on the upper and lower mounting plates. When the bed frame retracts, the locking tongue and latch engage to connect the upper and lower mounting plates, preventing accidental expansion. Attached Figure Description
